Description:

Note: Due to the large order backlog currently in place and problems with shipping assembled sliders, new orders will only be accepted for Rock SliderZ kits until further notice.

A popular add-on for 4x4s are nerf bars, that extend out from below the rocker panels. Sometimes called step bars, they are more for looks and convenience and I've seen on more that one occasion where the nerf bar bending under load can cause more body damage than the vehicle would of without the bar. For heavy duty use off-road, you really need something that will both protect your vehicle's body from damage and also keep you from getting hung up on an obstacle. Many people build their own bars and some companies are now offering heavy duty nerf bars or rock sliders. Most of these designs make use of welding the bar to the frame and rely solely on the strength of that weld and the support brackets to hold up the weight of the vehicle.

I used to run a rock slider from a now defunct company. These bars worked great and featured a bolt-on design that was more than strong enough for even hard core rock crawling. When I made some changes to my vehicle, I found it was necessary to either modify or replace the rock sliders. I chose to design my own version, correcting a few deficiencies in the original design and make it fit my modified vehicle better. So. I designed and built the 4Crawler Offroad Rock SliderZ for functionality:

Side view of Rock SliderZ

Here's what 4Crawler Offroad came up with. If you run run wider than stock tires and wheels, you can add 1" or 2" kicked out sections to the front and/or rear of the slider to helpslide off and away from rocks so the tires can grab them. This allows the center section of the bar to be just a bit wider than the body for protection, but no wider than absolutely needed. These are not some wimpy nerf bar, the 4Runner bars weigh in at about 35-50 lbs. each, other models more or less depending on length.

Underneath view showing mounting brackets

Here's a shot underneath, showing the outrigger braces from the outer to inner bar. The inner bar runs the full length from wheel well to wheel well providing full protection for the underside of the body. As a side benefit, it also hides the frame on body-lifted trucks. From the inner bar to the frame, you can see the two main supports. They bolt to the frame and provide more than enough strength to support the weight of the truck. The inner bar has another function, too. Under extreme loading, the bars will flex upwards until the inner bar contacts the body pinch weld, at which point the load is transferred to this very strong parts of the body. By spreading the load over the entire length of the pinch weld, there is little chance of damage occurring.

The underside of the bar is smooth from front to back, nothing sticks down any lower than the frame, the outer bar is cantilevered up at an angle for an additional 2" of ground clearance. The ends are tapered to slide on and off of rocks easier. All the ends are capped with heavy steel and all joints are fully welded to prevent internal corrosion. The bars themselves are available unpainted or in a paint finish that is easily touched up in the field.

Besides providing protection for the sheet metal on your truck, the bars also are functional as steps for ease of entering and exiting the vehicle, as well as for accessing items stored in on on top of the vehicle. The flat top of the square tubing provides secure footing and on painted bars, a 3M grip tape is installed for extra traction especially in wet conditions. I prefer the rubber tape to the more common grit tape since the rubber tape is much less abrasive, which you'll appreciate if you ever rub a bare leg across it!

Convenient step feature

I've been asked whether the ladder like outrigger bars get hung up on rocks on the trail. To date, I've never had any trouble with this. I've run my bars over some of the toughest trails in California, Oregon and Utah including the Rubicon, Fordyce Creek (Sierra Trek), the McGrew Trail, several trips through the Hammers in Johnson Valley, Dusy-Ershim, Moab Utah - including Pritchett Canyon, Rusty Nail and other trails, and have only once even seen a scratch on the ladder bars from a rock. My old American Metal bars had a similar ladder design and I ran those 3+ years without a problem.

Why did 4Crawler Offroad use a bolt-on design? There are a number of benefits:

Why does 4Crawler Offroad use a self-tapping bolt vs. a clamp-on mount?

So, is a bolted-on slider able to stand up to use and abuse on the trail? Have a look at the pictures below and see for yourself:

Specifications:

Fully bolt-on installation, dual tube 4Crawler Offroad Rock SliderZ are built of 2" x 2" and 1.5" x 1.5" steel tubing.

Straight 4Runner sliders

Optional kick-outs are available front and rear. With standard width wheels and tires, no kick-out if really needed (see image above), but if you are running wider than stock tires and wheels, then a 1" or 2" kick-out will help fill the transition from bar to tire. The inner tube of the bar serves an important function. These bars are designed to have a bit of flex. Under load, the bars will bend upward a bit, until the inner tube makes contact along the full length of the lower body-floor seam. By spreading the vehicle weight over the length of the bar, the load is transferred to one of the strongest parts of the body. Other nerf bar designs rely on absolutely rigid mounts such that the bar alone is supposed to be able to support the full vehicle weight. This often requires the bars be welded to the frame with heavy bracing and if not done properly, the nerf bars themselves can flex upwards and damage the body.

HiLift from the rearHi-Lift from the front

The acid test for these bars was to lift the side of the vehicle off the ground off the very end of the bar. Here, you can see the back tire lifted clear off the ground using a jack on the rear end of the bar. Similar results were obtained in the front end lift. You can see how the inner tube has made contact with the body seam in the right hand picture. This is by design and under extreme loads, they are designed to flex and transfer the load to the strong body seam. Also, note the big advantage of a square tube slider over a round tube design, no special adapter is needed for the jack.

Note:
The bars project a bit wider that the widest part of the body to keep the HiLift jack handle off the sheet metal.
While the picturws show HiLifting off the very ends of the bars, it is best to keep the jack inside one of the outrigger bars to keep it from sliding off the end of the bar if the vehicle or jack shifts while lifting.

So lifting the truck off the ground with the bar is interesting, but how do these things work on the trail?

Sierra Tested Tuff

Here's a closeup shot of the bars after their first trip off-road. A run to the local OHV park wasn't a valid test, rather, I took them over the infamous Fordyce Creek trail in the Sierra Nevada of northern California. Fordyce Creek is the trail used by the Sierra Trek for their short wheel base run. With my 106" wheel base, I figured I was near the 110" limit they impose on that run, so what better test. You can see in the above shot that the bars definitely saw some action. I had a couple of occasions to use the rear kick-outs, one time they probably kept me from rolling over. On another rock, I surfed the full length of the rock on the inner bar, wonderful sound of steel on granite the whole way over. Due to the smooth design, I slid over with ease and was even able to back up, turn and take a slightly different line, all the while with the driver's side of the truck fully supported on the bar. You can see the paint scratches all along the inner bar and the underside of the outrigger supports. Needless to say, I was totally pleased with the way these bars worked and would not change any part of the design for my rig.

Standard duty Rock SliderZCloseup of 0"-1" body lift version

However, for the less hardcore user, I have a less radical bar design. It uses 1/8" wall tubing throughout, reducing the weight and cost, while still offering adequate body protection.

For vehicles with stock width axles and running narrower tires, I also can make the bars without the kickouts (pictured above), which could potentially extend beyond the narrow tires and actually cause you to get hung up on the bar itself. In the above-left image, are a pair of standard duty Rock SliderZ and in the above-right image is a closeup of the mounting bracket for the 0"-1" body lift version. In this case, the outrigger legs are placed at the bottom of the frame and the bracket extends upward. In the 2"-3" version, the outrigger sits near the top of the frame and the bracket extends downward.

Pathfinder bars vs. factory steps SliderZ, rear view Sideward projection shot
Rock SliderZ vs. step bars Side view from the rear Sideward projection

The Pathfinder Rock SliderZ utilize all 6 factory step bar mounting holes, similar to the Xterra. Utilizing custom fabricated brackets to match the bends and angles of the factory step bars ensures a secure fit. Since there is no body/frame flex on the uni-body Pathfinder, the bars are set within 1/4" of the pinch weld seam to maximize ground clearance. Inner bar is 62" long. Check out Dean's Xplorx4 web page for more photos The sliders use the same standard and extra wide outer tube options, as offered on the Xterrra models, in order to be the same width as the factory steps for double use as a step and slider (extra wide) or a little narrower (standard width, extra cost), perhaps to add kickouts to.

Versions for the older hardbody Pathfinders are also available, they use self-tapping bolts for mounting.

For the Gen-I and Gen-II short and long wheel base Monteros, currently. For other models, inquire. Pictured below are two variations of the Gen-I and Gen-II sliders, the Gen-I are shown in a straight configuration, while the Gen-II are shown with optional kickouts for use with wider tires and/or factory fender flares. Either style slider is available in straight ot kickout versions, your choice. When straight sliders are ordered, the 4 outrigger supports are run out to the ends of the sliders, while the kickout version has them in about 12" from either end. Only difference between the Gen-I and Gen-II sliders are the location of the mounting brackets on the frame, otherwise width (about 1/2" wider than the widest extent of the door panel) and wheel-well to wheel-well length (~68") is the same. On the Gen-I/SWB sliders, the wheel-well to wheel-well length is ~53". Front mount is the same as on the LWB sliders, rear mount is moved forward to match the SWB frame.

The standard mounting bolt kit will include 2 self-tapping and 2 through-bolts (unsleeved) per bracket. The sleeved bolt kit will include 2 self-tapping bolts and 2 sleeved through bolts per bracket. The bars may also be welded to the frame, either stand-alone or after bolting to the frame for additional strength. A 1" weld bead along the bottom of each supprt bracket is sufficient.

Kickouts or not?

Kickouts refer to the last foot (12") of the outer tube of the sliders when it is angled outward, typically 1" or 2" from the rest of the tube. They are a useful addition to the sliders for off-road use. What they do is help to push the truck away from an obstacle to make it easier for the tire to grab it. They also help to protect the fenders, which can get damaged from sliding into a rock when you hit the end of a shorter set of sliders. Since many rock sliders have outer tubes that "dive" back towards the frame at the end, this can cause the truck to slide into a rock that you are maneuvering around. I had exactly this problem with my old round tube sliders, discussed below. One advantage of the kickout is that is keeps the sliders as narrow as possible (yet still protecting the body sheet metal) yet make the sliders a bit wider at the ends to help protect fenders and work with wider tires.

So how big to make the kickouts? The basic sliders are designed such that the outer edge of the outer tube is just wider than the widest part of the side of the body of the vehicle. So if you were to press your cheek to the side of the door panel and close the outside eye and peer down with the inside eye, you would just see the outer edge of the slider beyond the body sheet metal. Or if you were to hang a weighted string down vertically, the string would touch the slider perhaps 1/2" before contacting the body. Now, if you have wider than stock wheels/tires that project a significant distance wider than the body, measure how far the tire stick out. Then divide that distance in half for the ideal kickout width. So for a tire that stick out 2" wider than the body, a 1" kickout works well, for 4" wider tires, a 2" kickout can be used. Note that you want the distance the tires are wider than the door panel, not how far they are outside the fenders, most of the time.

One other use of kickouts is to clear fender flares, in which case you would want the kickount to be wide enough to clear the fender flare or to flow into it. This way the flare is offered some protection from off-road obstacles as you slide along them.

Kickouts are not required, the sliders work just fine without them, so if you don't want kickouts on your sliders, by all means order them made without kickouts. When built without kickouts, the outrigger support tubes are spread out such that they run almost to the front and back of the outer tube, rather than ending a foot from either end.

Mounting:

On vehicles that lack sufficient factory mounting holes, some method of attaching the Rock SliderZ to the vehicle frame is required. I offer three mounting options:

  1. Welding
  2. Self-tapping bolts
  3. A combination of self-tapping and sleeved bolts

Welding is probably the fastest (and easiest - if you have access to a welder) means to attach the bars to the frame.

Self-tapping bolts are the next in order of ease of installation. They require marking and pre-drilling holes in the frame for the bolts, which form threads as they are screwed into the frame steel. An installation kit is available (see below) to make pre-drilling for the self-tapping bolts nearly painless. It consists of an angle drill attachment that will work with any 1/4" (or larger) power drill (corded, cordless, air, etc.) and a short drill bit to allow drilling holes in confined spaces. Overall length is ~4.5" and is small enough to fit in even the tightest body-frame clearance. Cost is $40 for the kit, a $25 credit will be issued if it is returned in good condition. The special drill bit is designed for easy starting of the holes after marking with a center punch, then it enlarges the hole to the proper size for the self-tapping bolt, all in one step, no need to use a small bit to start, then a larger bit to finish the hole.

Installation Kit ($40)

*** Currently not available ***

If you desire a more substantial mounting scheme but still want to be able to remove the bars, a combination of self-tapping bolts (for the top of the brackets) and sleeved bolts through the frame for the bottom of the brackets is available. The upper self-tapping bolts are installed like above, but the lower thru-bolts require a hole be drilled through the frame followed by drilling a larger hole in the face of the frame for the sleeve to fit through. Then the sleeve is trimmed to the thickness of the frame and the thru-bolts installed. The sleeve prevents the frame from collapsing. If the bottom bolts are very hear the bottom edge of the frame, it may not be necessary to sleeve the hole as the frame rail will prevent collapsing.

Shipping:

Shipping weight is listed in the tables above and prices quoted are for UPS Ground delivery to the continental US only. Shipping costs to AK/HI and other destinations outside the continental US are higher. Note, the bars are all over 60" long and and ship UPS with oversize handling (ACH). You can get an estimate on shipping charge from the UPS web site oversize charges apply and they are shipped them from the customer counter at 94089. Add $20 per pair of bars for packaging for UPS Ground or pre-paid shipping (automatically added to the shopping cart when you select the appropriate button). Pre-paid shipping also includes interfacing with your shipper to hand over the packaged sliders to them. Local delivery is also available, contact me for details, but generally within 50 miles of San Jose, CA. and I can meet you part way for longer distances. You are welcome to pick up the finished bars as well. Use the pre-paid shipping option if you want to arrange for your own shipping (maybe you work for a company with a shipping discount or you have a lower cost carrier, whatever).

Note:
Shipping cost is added as a $0.01 cost item and the remainder as the actual shipping cost. This is done because PayPal doesn't allow $0.00 cost items and this way the shipping cost can be added without incurring sales tax for folks ordering sliders for delivery in California. Cost is based on UPS Ground, oversize/overweight package. Also for shipments to AK and HI and outside the US, shipping arrangements will need to be made separately, since these options are not covered in the above fixed charges.

Kits:

Mini-kit full kit
Mini slider kit Full slider kit

If you are able to do some basic welding or have a buddy who can weld, the bars are available in kit form with all parts pre-cut either with or without the long tubes. Without the long tubes, shipping cost is drastically reduced. The long tubes have simple 45 degree end cuts and 2" square tubing is readily available at local steel suppliers. Most will even custom cut tubing to your specifications for a nominal charge. In the above images, you can see the mini-kit on the left. Frome left to right, you can see the mounting bracket plates and gussetts, the mounting bracket legs (shown is a 2 mount kit, some kits will of course have 3 mounts per side), the outrigger bars and finally the end caps for the long tubes. In the full kit image to the right you see all the mini-kit parts below as well as the inner bars (top) and the outer bars (center). This kit is for an outer bar with kickouts and thus the ends the outer tubes has been cut an an angle to allow the kickouts to be formed when the short segments are welded back at the angle.

For the kit price, choose the bar model you want and subtract $60 for the full kit and subtract an additional $70 (i.e. $130 less) for a mini-kit (less long tubing sections). On the mini-kit, use the standard bar pricing, and realize that you will save a significant amount in shipping costs as well. Shipping weights are in the 18 lb. (2 short legs) - 30 lb. (3 legs or long leg kits) range and can ship to US addresses for $16 and to foreign addresses for $34-49 for kits to 20 lbs. and $68-$98 for kits up to 40 lbs. Allow approx. 3-4 weeks for cutting and shipping of the kit parts, depending on complexity and material availability. Full kit shipping cost is of course the same as quoted for assembled bars, as you are getting all the steel, just in pieces instead of all welded together.

For the mini-kits, you'll need to source the 2"x2" square steel tubing locally in whatever wall thickness you desire and you'll need an 4 lengths equal to the wheel well to wheel well distance on your truck. Contact 4Crawler Offroad for more information. Note that with current fuel prices, shipping costs for steel is about equal to the cost of the steel. So with mini-kits, the money you save in shipping the long steel tubes will essentially pay for the steel that you purchase locally, so the $130 cost savings on the mini-kit is money in your pocket.

We also offer a parts cutting list for selected slider designs so that you can supply your own steel, cut the parts to length and weld them up yourself. This saves on shipping the heavy steel. These parts cutting lists run US$20.00

NOTE: Due to high order volume, it may take some time for production and shipments to catch up. Order backlog could be up to 6 weeks.

Ordering, Fabrication and Delivery Time:

Note: Due to the large order backlog currently in place and problems with shipping assembled sliders, new orders will only be accepted for Rock SliderZ kits until further notice.

These sliders are made to order. Feel free to contact 4Crawler Offroad to discuss your application. Once the specifications are settled upon, payment can be arranged by check, money order, COD, and PayPal (via the on-line shopping cart ordering system). Fabrication time generally runs 10-12 weeks, although backlog is currently running approx. 6 months. Allow a few more days for painting and up to a week for shipping, depending on location. Delivery time can vary with order backlog, so the above time estimates are just that, estimates. Pre-paid orders are given priority in the queue, but if you prefer, you can place an order for COD delivery and pay for it when the sliders are ready. Paypal orders can be refunded in full if cancelled within 60 days, after that period, refunds will not include Paypal transaction fees (typically about 3%). Also, changes in orders are possible up to the time final assembly has begun, so don't hesitate to contact 4Crawler Offroad about changes if you feel you need to. If orders are cancelled once fabrication has commenced, a $50 fee will be deducted from the refunded amount. And if you can find a local welder, feel free to purchase your sliders in kit form, they can ship in approx. 3-4 weeks typically and you'll save on shipping costs as well.

Standard vs. Ultimate:

What's the difference? I use 1/8" (0.120) wall hot rolled electrically welded (HREW) tubing throughout for the Standard bars, while the Ultimate bars use 3/16" (0.188) wall tubing for the outer bar. You can see the two options in cross section below:

Standard and Ultimate tubing

The Standard tubing is plenty strong for most applications, its lighter in weight (saves on shipping cost). The Ultimate tubing has a thicker wall to stand up to continuous scraping over rocks, and since the wall thickness is greater, the radius of the corners are larger as well. In fact, you can see the corner radius is about 0.5", or the same as a 1" dia. round tube. This helps the tubing slide over rocks easier. Since it is the outside lower edge of the outer bar that sees most of this abuse, this is where the "beef" needs to be. An advantage over a round bar is that there is still a 1" wide flat spot on the top of the bar to allow application of grip tape for better traction when standing on the bar and no special adapters are needed to use a HiLift type jack on a square tube slider.

So why not use the heavier tubing for the rest of the bar in the Ultimate version? I don't feel the added weight and cost are justified in the other parts of the slider. For example the inner tube will only see contact along its base, so the rounder corner is not an advantage. In fact the rounder corner makes for a poor fit-up on the welded joints. Making the bars entirely out of the heavier wall tubing would increase their weight and cost by 50% and provide little added benefit. This is also the reason I don't go up to a 1/4" wall tubing, its just so much more added weight.

Which would I recommend? It all depends on how you plan use the sliders. If you wheel on mild and moderate trails and only need the sliders for occasional protection from trail obstacles, then the standard bar is fine. It'll protect the vehicle, provide a handy place to use a HiLift jack from, etc. If, you plan to run trails like the Rubicon, the Hammers or similar trails several times (or more) per year, then the thicker steel of the Ultimate bar is for you. These trails require the use of rock sliders for getting over the trail. They aren't merely for protection but become a tool to get across or around obstacles.

And why square tube and not round, isn't round tube stronger? Yes, round tube is about 18% stronger pound for pound than square tube. If weight and strength were the only considerations, round would be a good choice. Square tubing makes a more practical slider, works as a more secure step and makes a more secure HiLift jacking point without the need for a spacial adapter for the jack. Since the Rock SliderZ are designed to be multi-functional devices, square is much more useful. However, if interested, a round tube outer bar is an option for custom orders.

Background:

After I first started wheeling my 4Runner, I decided I wanted some rocker panel protection before I got into big rocks. I researched the options and found the American Metal Rock Sliderz nerf bars that seemed to fit the bill. They were strictly a nerf bar, not even close to being a step. They were bolt-on, low profile and were not meant to be totally rigid. In fact they were designed to bend and flex a bit, transferring the weight of the vehicle to a 4-5' length of the body seam. Unlike single tube bars that can cause as much damage to the body when they flex, the Rock Sliderz were designed to distribute the load over a large area to prevent localized damage. In 2 years of hard 4-wheeling, I never had a scrape or dent to the rocker panel area, nor did the bars dent, bend or suffer any damage aside from some scratched paint.

So, why did I replace them if they were so good? A number of reasons:

  1. First they were only suitable for 0-1" of body lift. Any more lift and you could not get the inner bar close enough to the body to function properly. I was planning a 3" body lift and wanted to gain the full 3" of additional side clearance.
  2. The old bars dove back into the frame at the ends, which would end up sucking the vehicle towards a rock that you were trying to climb. I wanted to have a "kick-out" at the ends of the bar to push the vehicle away from the rock to allow the tire to climb better.
  3. Because of the design of the body and the outer bar returning to the inner bar, installation required that a half-moon of sheet metal be removed from the body seam for proper fit. Out in the drier west coast, rust is not an issue, but if this was done in the rust-belt, it is in a very bad place, right in front of the rear wheel.
  4. The old bars were a bit too narrow, there were times I had wished they were a few inches wider, they were actually an inch or two narrower than the widest part of the body.
  5. Finally, while I wasn't looking for a step bar, the old bars, being so close to the body and round, were almost impossible to step on, and if your feet were wet, they were downright dangerous. So, adding that all up, I decided I would be better off selling the bars and designing my own.
  6. Also, with the round tubes, a special adapter is needed for the use with a HiLift type jack.
