6mm Heavy-Duty Aluminum. Precision 149.4" Wheelbase Fit. 100% Bolt-On Armor.
Maximum Security for Your HD Fuel SystemThe ASFIR 4X4 Fuel Tank Skid Plate is the definitive insurance policy for your 2020+ Chevrolet Silverado or GMC Sierra 2500 HD. While the 6.6L Duramax provides the power to move mountains, its 29-gallon fuel tank remains a massive, vulnerable target when navigating jagged rocks, deep ruts, or high-centering trail hazards.
Precision-engineered and trail-tested in extreme desert conditions, this armor is crafted from 1/4" (6 mm) laser-cut aluminum. It delivers the heavy-duty shielding required for serious work and play without the rust and weight penalties of traditional steel plates.
Why ASFIR Protection:The Pain: Heavy Duty trucks have a significant "belly" that frequently drags over obstacles. A punctured 29-gallon tank is not only a $2,500+ repair but a major safety risk in remote areas.
The ASFIR Solution: Lightweight, reinforced 6mm aluminum armor that allows your truck to slide over obstacles while keeping your fuel supply safely contained.
Key Features: Precision HD Protection
Direct bolt-on design utilizes existing factory mounting points on the 2500 HD chassis. No permanent modifications are required.
Laser-cut 1/4" aluminum provides industrial impact resistance while keeping total weight to only 31 lbs—significantly lighter than steel armor.
Integrated drain holes and ventilation slots prevent mud, water, and heat buildup against the fuel tank housing.
Marine-grade aluminum construction paired with zinc-coated steel brackets ensures your armor stays rust-free for the life of the truck.
Tested for Real-World DurabilityASFIR 4X4 armor isn't just about looks; it's battle-tested in the world's harshest off-road environments. This plate features structural stiffening ribs to increase vertical strength, ensuring the aluminum absorbs impact rather than deforming into the tank.

"The fuel tank on the 2500 HD sits lower than people realize. I installed the ASFIR plate before a towing expedition through the Rockies. We ended up on some tight shale trails and I took a massive hit to the mid-section. The plate took the scrape and didn't dent a bit. Knowing that 29 gallons of diesel was safe was worth every penny. Install was simple and bolt-on as promised."

No. This skid plate is precision-measured for the 149.4" wheelbase Double Cab configuration. Long bed models utilize a larger 36-gallon fuel tank and have different mounting hole spacing.
No. This is a 100% no-drill installation. It utilizes the factory threaded holes and mounting points already present in the GM 2500 HD chassis.
6mm aluminum is the industry standard for high-end off-road armor. While steel is slightly harder, it is significantly heavier and prone to rust. Aluminum absorbs impact energy better and will never rust, making it superior for long-term chassis health.
The ASFIR plate is designed to hug the fuel tank as closely as possible. You will experience negligible clearance loss (less than 0.25"), which is far outweighed by the smooth surface that allows the truck to slide over obstacles.
Yes. This fuel tank skid plate is fully compatible with ASFIR's complete underbody protection system, including engine, transmission, and transfer case plates for the Silverado and Sierra HD.

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
