Heavy Trail Tested. Industrial Primer Protected. 100% Bolt-On Performance.
Traverse Obstacles with Absolute ConfidenceTurn Offroad’s Zero Series Rock Sliders were designed and tested with heavy trail use in mind. These sliders provide maximum ground clearance and incredible protection when navigating technical terrain. Whether you're dropping off a ledge or pivoting around a boulder, these sliders are built to take the hit so your Bronco doesn't have to.
Design and R&D were focused on achieving a tight fitment that complements the Bronco’s lines while maintaining a simple, 100% bolt-on installation. Engineered for the 2021+ 4-Door Ford Bronco, these are the ultimate upgrade for the serious off-roader.
The Problem & The Solution:The Pain: Factory "rock rails" are often thin-walled and offer little protection against heavy impacts, while many aftermarket sliders rust from the inside out or require drilling into your new frame.
The Zero Series Solution: We use .160 wall tubing and a unique industrial primer dip process to protect the steel structure beneath our three-stage powder coat, all while utilizing factory mounting points.
Key Features: Engineered Strength
Designed with boxed ends to provide superior structural rigidity and prevent hang-ups on sharp rocks.
Integrated dimple dye reinforcing plates add massive strength without unnecessary weight, while looking aggressive.
No drilling, no welding, no headaches. This kit is designed for a simple, direct bolt-on fit to your Bronco's frame.
Tucked tight to the body to ensure maximum breakover angle and clearance while traversing steep obstacles.
Prior to powder coating, every slider is dipped in industrial primer to seal and protect the internal steel from corrosion.
Finished with a three-stage protective nano-textured powder coat for a durable, non-slip, and premium aesthetic.
Heavy-duty construction using thick .160 wall tubing ensures these sliders won't flex or fail under pressure.
Mounting is handled by over-engineered 1/4" and 3/16" brackets for a rock-solid connection to the vehicle.
Over-Engineered ProtectionWe don't just build armor; we build confidence. The strength of the Zero Series comes from the **center supporting beams** and the precision engineering of every weld. Every aspect of this slider has been refined to provide maximum protection for your 4-Door Bronco's rocker panels.

"The fitment on the Zero Series is incredible. They sit high enough that I don't lose any ground clearance, but they're beefy enough that I stopped worrying about my rocker panels on the rocks. The nano-texture finish is top-notch and was a true bolt-on install—I had both sides done in under two hours."
- Mike S., Bronco Badlands Owner Important Fitment NoteCheck Your Vehicle: These rock sliders are designed specifically for 2021+ 4-Door Ford Broncos ONLY. They will not fit 2-Door models or Bronco Sport models.

2021+ Ford Bronco 4-Door (All Trims) Sasquatch & Non-Sasquatch PackagesKey Tip: These sliders replace factory rock rails or side steps. All necessary hardware is included for a seamless transition to heavy-duty protection.
No, the RS1-M4 model is specifically sized for the wheelbase and mounting points of the 4-Door Bronco Only.
No drilling is required. These sliders are designed to be a bolt-on installation using existing factory locations.
Standard powder coating can chip on the trail. Without a primer dip, moisture reaches the raw steel and causes rust to spread under the coating. Our primer dip ensures the steel remains protected even if the outer coat is scratched.

Prop 65 Warning- Product may contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov
Proposition 65 is a California law passed in 1986. Its goals are to protect drinking water sources from toxic substances that may cause cancer and birth defects and to reduce or eliminate exposures to those chemicals generally, for example in consumer products, by requiring warnings in advance of those exposures.
The regulation requires the State of California to revise and republish yearly a list of chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. The current list contains over 900 naturally occurring and synthetic chemicals. This regulation also requires manufacturers to place warnings on products that contain any of the chemicals listed by the State of California. No other states require warnings of this nature, and products with Prop 65 warning language are legal to sell in all states. Detailed information regarding requirements for compliance to the California Prop. 65 is can be found at: www.P65Warning.ca.gov

Here's why we think you should shop with us at ExtrailAuto.
The wait time was more than I anticipated even after seeing the notification of long lead times. I have to give them props for giving some compensation for the excessive wait time. Having slightly larger holes would help with fitment. Had a hard time getting the front drivers side away from the pinch weld. Eventually had to use washers to add space away from the truck. Need to update pictures and instalation video for the new sliders they are now making
All packing and shipment were great, everything was there. I had to contract out the install because of arthritis, it took them two hours and looks perfect. Zero wind noise at any speed 0 to 100.
Absolutely love my new rack and roam cases. Appreciate the Sherpa crew as well for their hospitality while the installation was taking place.
Fit and finish is excellent. Looks great on the Bronco. No whistling noise at all, some additional wind noise over 60mph but not much different than it was without the rack. Assembly was not too difficult. Instructions and videos could be a little better.
The quality and dedication of the team at Sherpa is evident from the very first interaction with them, and is further proven in the product itself. This rack is well engineered, easy to assemble, easy to adjust, and holds up incredibly well with no loosening or rattling or shifting (even after over 200 miles of driving on poorly maintained roads). Currently operating with approximately 180 pounds of gear mounted on the bed rack and no issues at all so far. I expected the vibration to work the bolts loose over time, but every time I check they're all still snug. My only regret is that I didn't pull the trigger and get this rack sooner.
First of all, the team at Sherpa is full of passion for adventure and that passion shows in the quality of their products. This roof rack looks incredible and surprised me with it's sturdiness. No loosening of hardware, even after weeks of driving. Currently holding approximately 80 pounds of gear for everyday driving, plus an additional 110 strapped on top during a camping trip (and I even stood on top of the entire loadout). No warping, bending, twisting, or slipping. The fact that this matches the bed rack perfectly in height is the icing on the cake. Easily serves as a tie off for a tarp, rain fly, hammock, or whatever you need. Perfect for modular campsite setup and quick teardown.
I bought the Sherpa Crestone rack for my 2024 4Runner TRD Pro. Incredibly well-made and excellent design. Spend the extra , to get best roof rack in the market. You won’t regret it.
This is our first roof rack that we are going to use to put a RRT (roof top tent) on for back country trips. Well-built product that came with all the nuts, bolts and washers to complete the installation. Took about 1-1/2 to 2 hours install the rack. You will another person to help place the racks on top of the Jeep for final install. Overall, a great, well-built American product
Install was super easy. The quality was great. Customer service was quick to respond to any issues! I’ve already been getting compliments on it and what brand it is. This will be great for camping this year!
This is on my tundra absolutely solid rack looks fantastic extremely modular, which is why I went this route. I can use the whole rack when traveling and over landing then rock the chase rack only when the rest is not in use, I actually use the recovery traction board mounts for my shower room set up, which works amazingly just relocated the board somewhere shown in picture keep innovating TUWAand I’ll keep purchasing.
Good looking cat shields made of stainless steel with cooling holes. Priced well, easy install, no issues. Would buy again.
Great service from their staff. Robert help me through all the process with a request I had, he responded all emails in a timely manner and provided great help.
We received it within 3 days and installed the same day. Great awning and very well made.
the tent is very nice, comfortable and roomy.
Following the instructions was fairly easy. Its better to have second person to set it up. I really like the tent and the support that from ExtrailAuto. Really recommeded! Thanks
