Premium 6mm Aluminum Armor. 100% Bolt-On. Powertrain-Specific Protection.
Heavy-Duty Protection for Advanced DrivetrainsThe Asfir 4x4 Engine & Transmission Skid Plate is precision-engineered to safeguard the most complex powertrains in the Jeep lineup. Whether you are piloting the high-torque 3.0L EcoDiesel or the advanced 2.0L 4XE Plug-In Hybrid, your underbody components are exposed to trail hazards that can end an adventure in seconds.
Manufactured from premium 1/4" (6 mm) laser-cut aluminum, this armor provides maximum structural defense while remaining significantly lighter than traditional steel. Designed to wrap around the engine oil pan and transmission housing, it offers a smooth sliding surface for rocks without sacrificing ground clearance or adding unnecessary bulk to your hybrid or diesel setup.
The High-Stakes Challenge:The Pain: Modern EcoDiesel and 4XE components are incredibly expensive to replace. A single rock strike to the transmission or diesel exhaust system can result in a total powertrain failure and thousands in repair costs.
The Asfir Solution: Powertrain-specific geometry, reinforced stiffening ribs, and a 100% Bolt-On design that ensures your vital components remain untouched on the trail.
Key Features: ASFIR Underbody Defense
Designed for a perfect fit using existing factory mounting points. Maintains your vehicle's structural integrity and resale value.
High-strength aluminum provides the impact resistance of steel but is nearly 40% lighter, preserving your hybrid range and diesel efficiency.
Pressed structural ribs add immense rigidity, preventing the plate from bowing under the weight of the vehicle during high-impact rock strikes.
Custom-cut vents manage heat dissipation for sensitive hybrid batteries and diesel exhaust systems, preventing overheating during low-speed crawling.
Drain holes are strategically placed to release trapped water, dirt, and mud, making underbody cleaning effortless after the trail.
Natural aluminum is rust-proof, supported by zinc-coated steel brackets to withstand road salt and harsh off-road conditions.
Engineered Specifically for Modern JeepsGeneric skid plates often fail to account for the unique cooling lines and exhaust routing of the 4XE and EcoDiesel models. Asfir 4x4's engineers have tested these plates exclusively on these powertrains to ensure a precise, zero-interference fit. This is the ultimate "install and forget" insurance policy for your Jeep.
20-24 lbs Lightweight Armor 6mm Thickness 4XE / Diesel Custom Fitment Zinc-Coated Steel Brackets
"Finding a skid plate that fits the 4XE without interfering with the electric cooling lines was a mission. Asfir nailed it. The install was truly bolt-on and the weight is so low that I didn't lose any of my EV mileage. I've dragged my 3.0L Gladiator over several shelves in Moab and the plate didn't even flinch. It's the best investment for a heavy diesel Jeep."

Precision fit for the following Wrangler JL and Gladiator JT powertrains:
Jeep Wrangler JL 4XE PHEV (2021-2023): 2.0L Plug-In Hybrid. Jeep Wrangler JL EcoDiesel (2020-2023): 3.0L Diesel 4-Door. Jeep Gladiator JT EcoDiesel (2021-2023): 3.0L Diesel 4-Door.Package Includes: High-grade aluminum skid plate, zinc-coated mounting brackets, and all premium installation hardware.
Asfir designs their engine skid plates with integrated access points or geometries that minimize interference. However, for a complete and clean oil change on EcoDiesel or 4XE models, some users prefer to briefly drop the plate, which is easily done thanks to the simple bolt-on design.
No. This specific plate is designed to clear the unique exhaust and cooling architecture of the EcoDiesel and 4XE. For the standard gas engines, please select the Asfir skid plate specifically designed for those engine literals.
Absolutely. 6mm (1/4") aluminum is the professional standard for aluminum armor. When reinforced with pressed stiffening ribs like the Asfir plate, it provides exceptional impact resistance that can handle the full weight of the vehicle dropping onto a rock.
No. Asfir has engineered specific ventilation slots to ensure airflow reaches the engine and transmission. This is especially critical for the 4XE's electric components and the EcoDiesel's higher operating temperatures.
Yes, the skid plate mounts directly to the chassis/frame, so it is generally compatible with suspension lifts and most aftermarket bumpers that do not occupy the same frame-mounting real estate.

California Residents
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

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
