6mm Heavy-Duty Aluminum. No-Drill Installation. Trail-Proven Drivetrain Armor.
Maximum Underbody Defense for Your JLThe Asfir 4x4 Engine & Transmission Skid Plate is the ultimate insurance policy for your Jeep Wrangler JL. Engineered to protect the most vulnerable and expensive components of your drivetrain, this plate is laser-cut from 1/4" (6mm) high-quality aluminum.
Manufactured with precision, Asfir armor provides superior impact resistance while maintaining an optimal strength-to-weight ratio. Unlike heavy steel plates, this aluminum shield protects your oil pan and transmission without sagging your suspension or compromising your Jeep's off-road agility.
The Problem & The Solution:The Pain: The factory JL protection is often insufficient against jagged rocks, leading to cracked oil pans and stranded Jeeps. Steel armor is heavy and prone to rust.
The Asfir Solution: We use marine-grade aluminum and a 100% bolt-on design. Integrated stiffening ribs deflect massive hits, while precision vents prevent heat soak in your transmission.
Technical Features: Engineering Excellence
Naturally corrosion-resistant aluminum alloy ensures your armor won't rust, even after taking deep scratches on the trail.
Mounting brackets are heavy-duty steel with a zinc coating, providing long-term resistance to salt and environmental oxidation.
Designed to hug the JL chassis tightly, ensuring minimal loss of ground clearance for superior break-over angles.
Includes a strategically placed port to allow for oil drainage without needing to remove the entire skid plate system.
Tested in the World's Harshest DesertsWhether you are running the standard 3.6L Gas or the MHEV (Mild Hybrid) version, Asfir has tailored this plate for precision fitment. It covers the engine oil pan and the transmission casing, creating a smooth surface that lets you slide over obstacles that would otherwise snag a factory setup.
26 lbs Lightweight 6mm Alu Thickness Bolt-On No Drilling
"The install was incredibly straightforward for a bolt-on kit. I've taken several hits on the rocks in Moab, and the aluminum plate just has a few scuffs. It's much lighter than my buddy's steel plate, and it doesn't rattle. The cooling vents are a nice touch for the transmission!"

Yes, this skid plate is precisely engineered to fit both 2-door (SWB) and 4-door (LWB) Jeep Wrangler JL models equipped with the 3.6L engine.
Yes. We have integrated service access points that allow for engine oil drainage without having to remove the entire skid plate system.
Manual models must have the factory manual-specific crossmember. Please check the fitment photo in the description above to verify your vehicle has the correct mounting point.
While steel is harder, our 6mm thick aluminum is designed to absorb and deflect hits by flexing slightly rather than transferring 100% of the force to the frame. It provides a smooth sliding surface and is much better for overall vehicle dynamics.
Typical installation time is between 45–90 minutes with basic hand tools. No professional drilling or welding is required.

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
We get it. You've got a lot of choice when it comes to online retailers.
Here's why we think you should shop with us at ExtrailAuto.
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
