Chassis-Mounted Steel Armor. Integrated Side Step. Hi-Lift Jack Compatible.
The Ultimate Rocker Defense for 4-Door BroncosThe ASFIR 4X4 Ford Bronco Rock Sliders are not your average decorative running boards. These are heavy-duty tactical guards engineered to survive the world's most demanding trails. While others focus on looks, ASFIR focuses on structural survival—shielding your rocker panels and lower doors from catastrophic impact.
Built from premium high-strength steel and reinforced with a solid steel bar, these sliders weigh in at a substantial 101 lbs. This mass is a testament to their strength, providing a rigid barrier between the earth and your vehicle's expensive bodywork.
Why ASFIR Sliders?The Pain: Factory steps and body-mounted guards fold under pressure, often causing more damage to the rocker panel than the rock itself.
The ASFIR Solution: These sliders mount directly to OEM chassis points. This transfers the force of an impact to the frame, not the body, and provides a stable platform for Hi-Lift jacking.
Key Features: ASFIR Steel Rock Sliders
Strong enough to support the weight of the vehicle. Use your Hi-Lift jack anywhere along the slider for emergency repairs.
Reinforced with a solid steel internal bar for maximum rigidity and resistance against heavy trail strikes.
The wide profile and textured grip provide a safe, stable step for passengers and roof rack access.
Bolts directly to factory-drilled chassis holes. Preserve your Bronco's frame integrity and resale value.
Dual-stage coating designed to withstand harsh off-road environments and road salt exposure.
Designed to follow the Bronco's body lines while acting as a pivot point for tight technical turns.
Built for the Toughest TerrainUnlike aluminum protectors, these steel sliders are meant to be used as a sliding surface. When you are high-centered, the solid steel bar allows you to slide off obstacles without crushing your rocker panels. ASFIR armor is tested in the harshest desert environments on Earth.

"I've gone through two sets of aluminum 'side protectors' that both bent the first time I hit a real rock. Switched to the ASFIR steel sliders and the difference is night and day. These things are tanks. Having the ability to use my Hi-Lift jack on the slider gives me so much more confidence when I'm out solo."

These are chassis-mounted. Body-mounted steps can bend the rocker panel during an impact. By mounting directly to the frame, the ASFIR sliders transfer the energy of a strike to the strongest part of the vehicle.
These sliders are designed with a high-clearance profile. While any slider sits below the rocker, the ASFIR design is tightly tucked to the body to minimize ground clearance loss while providing a smooth sliding surface for rocks.
Yes. These rock sliders are Hi-Lift jack compatible. Because they are chassis-mounted and reinforced with a solid steel bar, they are strong enough to support the weight of the vehicle for off-road recovery and tire changes.
The ASFIR Rock Sliders weigh 101 lbs (46 kg) for the pair. This weight is necessary for true rock-sliding capability and Hi-Lift compatibility, which lightweight aluminum steps cannot provide.
No. These sliders are 100% bolt-on. They utilize the factory mounting holes already present in the Bronco's chassis, making installation straightforward and non-destructive.

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

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
