6mm Heavy-Duty Aluminum. 157" Wheelbase Precision. 100% Bolt-On Armor.
Critical Defense for the 157" Crew CabThe ASFIR 4X4 Fuel Tank Skid Plate is engineered to safeguard one of the most vulnerable areas of your Chevrolet Silverado or GMC Sierra 1500. On the 157" wheelbase Crew Cab configurations, the fuel tank represents a massive, low-hanging target that is susceptible to high-centering and trail debris.
Precision-manufactured and tested on 5.3L gasoline models, this skid plate is crafted from 1/4" (6 mm) laser-cut aluminum. It provides the heavy-duty shielding required for serious off-roading without the excessive weight of steel, ensuring your truck remains efficient and agile on or off the pavement.
Why ASFIR Protection:The Pain: Crew Cab trucks have a long "belly" that frequently bottom-out on trail crests. A punctured fuel tank isn't just a $2,000 repair; it's a safety hazard and a trip-ender.
The ASFIR Solution: Lightweight aluminum armor reinforced with structural ribs that allow your truck to slide over obstacles while keeping your fuel supply safe.
Key Features: Precision Fuel Tank Protection
Designed to bolt directly to the chassis using existing factory mounting points. No drilling or cutting means your truck maintains its structural integrity and resale value.
Laser-cut 1/4" aluminum offers an incredible strength-to-weight ratio, protecting your tank without adding the 80+ lbs associated with steel plates.
Engineered with integrated stiffening ribs that provide maximum rigidity, ensuring the plate protects against heavy vertical impacts and dragging.
Strategic ventilation slots and drain holes ensure that mud, water, and trail debris clear easily, preventing long-term corrosion or moisture retention.
Tested for Real-World OverlandingASFIR 4X4 armor is tested in the world's most unforgiving terrains. This fuel tank plate accounts for the Silverado/Sierra's specific chassis geometry, hugging the tank to ensure you don't lose approach or breakover angles while gaining industrial-grade protection.

"The Crew Cab 1500 has such a long wheelbase that I was constantly worried about the fuel tank catching on rocks. The ASFIR plate was a perfect fit. It's so much lighter than the steel options, so my MPG didn't take a hit. Already took a big scrape on some granite, and the plate didn't even flinch. Install was a breeze."

No. This skid plate is precision-measured for the 157" wheelbase Crew Cab configuration. The mounting points and plate length are specific to this geometry and will not align with shorter wheelbase models.
No. This is a 100% no-drill installation. It utilizes the factory threaded holes and mounting points already present in the GM 1500 chassis architecture.
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 protection.
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 rather than getting hung up.
Yes. At only 28.6 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
