6mm High-Grade Aluminum. No Drill Installation. Precision 31-Gallon Protection.
The Ultimate Shield for Your RAM 3500's Fuel SystemThe ASFIR 4X4 Fuel Tank Skid Plate is engineered specifically for the 2020-2024 RAM 3500 Double Cab SWB models. While the 6.7L Cummins provides the torque to conquer the trail, the fuel tank remains a massive, low-hanging target. Factory plastic guards are insufficient against jagged rocks and high-centered stumps that can end an expedition instantly.
Precision-manufactured and trail-tested in extreme desert environments, this skid plate is crafted from 1/4" (6 mm) high-grade aluminum. It delivers heavy-duty shielding required for serious work and play without the massive weight and rust potential of traditional steel plates.
The Problem & The Solution:The Pain: RAM Heavy Duty trucks have a significant "belly" that frequently bottom-out on trail crests. A punctured fuel tank isn't just a $2,500 repair; it's a fire hazard and a trip-ender.
The ASFIR Solution: We use a 100% Bolt-On design and lightweight, reinforced 6mm aluminum armor that allows your truck to slide over obstacles while keeping your fuel supply safely contained.
Key Features: Precision Fuel Tank Protection
The ASFIR kit uses a 100% bolt-on assembly, utilizing existing factory mounting points to preserve your RAM's frame integrity and resale value.
Laser-cut 1/4" aluminum offers an incredible strength-to-weight ratio. At only 37 lbs, it protects without sagging your suspension or affecting payload.
Engineered with integrated stiffening ribs that maximize rigidity, ensuring the plate protects against heavy vertical impacts and dragging.
Naturally rust-proof aluminum construction paired with zinc-coated steel brackets ensure your armor never rusts, even in salt-heavy environments.
Tested in the World's Harshest TerrainASFIR armor isn't just for show. This plate is specifically designed to complement the RAM 3500 HD's chassis architecture. By using zinc-coated steel brackets for the main supports, we ensure the hardware remains corrosion-free and the plate stays securely fastened even after repeated technical rock crawling hits.

"The fuel tank on my RAM 3500 was sitting out there like a target. I installed the ASFIR plate in about 45 minutes. It feels solid as a rock and the fit is incredibly clean. I've already taken a hit on a hidden stump and the plate didn't even flinch. Best peace of mind you can get for the price."
- Brandon K., RAM 3500 HD Owner Important Fitment NoteCheck Your Build: This skid plate is specifically designed for 4x4 Double Cab models with the 31-gallon (117-liter) fuel tank and rear coil springs. Verification of tank size is recommended before purchasing.

No. This specific plate is precision-cut to clear rear coil spring components. Vehicles with factory rear air suspension have different mounting requirements and clearances around the fuel tank area.
No. This is a 100% no-drill installation. It utilizes the factory threaded holes and mounting points already present in the RAM 3500 frame architecture.
Yes. 1/4" (6mm) aluminum is the industry standard for high-end off-road armor. It provides excellent impact resistance and absorbs shock energy better than steel, while being much lighter and rust-proof.
No. The ASFIR plate is designed with drainage holes and vents. These allow mud, water, and trail debris to clear out easily during cleaning, preventing long-term corrosion or moisture retention against the tank.
Yes. At only 37 lbs, the plate is light enough to be managed by one person using a floor jack for support. Installation typically takes 30 to 60 minutes with basic hand tools.

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
