6mm Heavy-Duty Aluminum. Direct Bolt-On. Essential 4WD Shielding.
Armor for the Heart of Your 4WD SystemThe ASFIR 4X4 Transfer Case Skid Plate is the ultimate insurance policy for your Chevrolet Silverado or GMC Sierra 1500. While these trucks are engineered for heavy-duty work and trail exploration, the transfer case remains one of the most vulnerable and expensive components of your drivetrain.
This plate is laser-cut from high-grade 1/4" (6 mm) aluminum. It is specifically designed for 2019+ Crew Cab models, providing industrial-strength impact resistance without the rust or weight penalties of traditional steel plates.
Why ASFIR Protection:The Pain: The transfer case sits low and is often exposed to "high-centering" on rocks or stumps. A single crack in the housing results in immediate fluid loss and 4WD failure.
The ASFIR Solution: Lightweight, reinforced 6mm aluminum armor that absorbs impact energy and protects your case while maintaining maximum ground clearance.
Key Features: Transfer Case Armor
Designed to bolt directly to the chassis using existing mounting points. No permanent vehicle modification required.
Laser-cut 1/4" aluminum provides extreme impact defense while keeping weight at a mere 17.6 lbs.
Structural ribs are pressed into the aluminum to increase rigidity, ensuring the plate protects against heavy vertical strikes.
Strategic slots and drain holes allow heat to escape while enabling water, mud, and trail debris to clear easily.
Tested in Extreme TerrainASFIR armor isn't just about looks; it's battle-tested in the world's harshest off-road conditions. By using zinc-coated steel brackets for the main supports, we ensure the hardware remains corrosion-free and as tough as the plate itself.

"The transfer case on my Sierra 1500 was sitting there wide open. I installed the ASFIR plate in about 30 minutes. It feels solid as a rock and the fit is incredibly clean. I've already taken a few scrapes on fire roads and it hasn't dented or vibrated at all. Best peace of mind you can get for the price."

Fitment: 2019+ GM 1500Precision-engineered for the modern Chevrolet and GMC 1500 chassis. Fits the following specifications:
Silverado 1500 (2019+) Sierra 1500 (2019+) Crew Cab Models OnlyEngine Note: Tested and verified for the 5.3L Gasoline V8. Compatible with 4WD configurations.
CA Residents: ⚠️ WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
While it was specifically tested on the 5.3L, the transfer case position is generally the same across the 1500 Crew Cab platform. However, we recommend verifying your mounting point clearance before installation.
No. This is a 100% bolt-on installation. It utilizes the factory threaded holes and mounting locations already present in your Silverado or Sierra frame.
Yes. 1/4" (6mm) aluminum is the industry standard for high-end off-road armor. It provides excellent impact deflection and absorbs shock energy better than steel, while being much lighter and rust-proof.
No. The plate includes integrated drain holes. Most routine checks and maintenance can be performed with the plate on. If full removal is required, it takes less than 10 minutes due to the simple bolt-on design.
This skid plate is extremely lightweight at only 17.6 lbs. It provides maximum protection for your transfer case without negatively impacting your payload or fuel economy.

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
