Heavy-Duty Protection for Specialized Engines. 100% Bolt-On. 1/4" Aluminum Armor.
Armor for the Toughest JL PowerplantsThe Asfir 4x4 6-Piece Skid Plate Kit is specifically engineered for the high-performance variants of the Jeep Wrangler JL: the 3.0L EcoDiesel and the 6.4L V8 392. These models feature unique underbody architectures, from the low-hanging Urea tank on the Diesel to the massive oil pans on the 392, requiring protection that standard JL kits simply can't provide.
The skid plates kit uses 1/4" (6mm) laser-cut aluminum. It provides world-class impact resistance while keeping weight significantly lower than steel alternatives, ensuring your suspension and fuel economy aren't compromised by your armor.
The Problem & The Solution:The Pain: Specialized JL engines have expensive, vulnerable components. A rock strike to a 392 oil pan or a Diesel Urea tank can end your trip and cost thousands in repairs.
The Asfir Solution: Custom-fit shielding for engine, transmission, transfer case, fuel tank, and differentials—built specifically for the 3.0L and 6.4L platforms.
Key Features: Total Drivetrain Security
Tested exclusively for the 3.0L Diesel and 6.4L V8 engines. Compatible with both aluminum and steel oil pans on 392 models.
100% bolt-on assembly. Uses existing factory mounting points, requiring zero drilling, welding, or cutting of your frame.
Premium 6mm aluminum construction provides maximum strength for rock crawling while minimizing added weight.
Integrated stiffening ribs provide superior impact resistance in high-stress zones where standard plates might buckle.
Zinc-coated steel brackets ensure a rock-solid, corrosion-resistant connection to the vehicle's frame.
Precision-cut ventilation slots maintain critical airflow for cooling while allowing mud and debris to drain.
Includes both front and rear Dana 44 differential skids to protect your axle housings from low-profile hazards.
Aluminum construction and zinc-coated hardware prevent the rust issues common with traditional steel plates.
Optimized for Power & PerformanceWhether you’re managing the torque of the 3.0L EcoDiesel or the raw power of the 392, weight distribution is key. This 6-piece kit balances extreme protection with a lightweight footprint (79 lbs for Diesel / 98 lbs for 392), ensuring your Jeep remains agile on the trail.
79-98 lbs Lightweight Armor 1/4" (6mm) Aluminum Strength 6-Piece Full Coverage Bolt-On No Drilling
"The EcoDiesel has a lot of 'dangly bits' underneath like the urea tank. The Asfir kit covered everything perfectly. I've dragged these over rocks in Moab and they hold up brilliantly. The best part? No drilling into my brand new frame. Worth every penny."

Specifically designed for the higher-output 4-door Wrangler JL models:
2020 - 2023 Jeep Wrangler JL EcoDiesel (3.0L) 2020 - curent Jeep Wrangler JL 392 (6.4L V8)Important Note: The Exhaust/Urea skid plate (547580) for the EcoDiesel model is compatible with the rear plastic bumper only.
The Asfir engine skid plate (547556) is engineered to fit both the standard aluminum and steel factory oil pans. If you have a significantly deeper aftermarket pan, please contact us for specific clearance dimensions.
The Urea Tank skid plate (547580) mounts using geometry that aligns with the factory plastic rear bumper. Many steel bumpers use different mounting points or include their own structural reinforcement that interferes with this specific skid plate's bracketry.
Yes. Marine-grade 6mm aluminum is the preferred choice for many overlanders. It is thick enough to handle significant impacts and slides over rocks better than steel. Additionally, it has a "memory" that resists permanent deformation better than thin steel plates.
No. Both the EcoDiesel and 392 run hot. Asfir has integrated large ventilation apertures into the design to ensure hot air can escape and cool air can reach the drivetrain, preventing thermal issues during slow, high-torque crawling.
Yes. Because the kit is 100% bolt-on and aluminum is relatively lightweight, a single person can install these with a floor jack and basic hand tools. Total installation time is typically 3-4 hours.

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
