Hybrid-Specific Protection. 1/4" Aluminum. 100% Bolt-On Performance.
Rugged Defense for the Advanced Hybrid DrivetrainThe Asfir 4x4 3-Piece Underbody Protection Kit is purpose-built for the Jeep Wrangler JL 4XE PHEV. Your hybrid Jeep carries advanced electrical systems and a unique powertrain that demands specialized shielding. This kit delivers rugged defense against rocks, debris, and trail hazards without sacrificing the efficiency of your PHEV.
Crafted from 1/4" (6mm) laser-cut aluminum, this kit guards your engine, transmission, transfer case, and fuel tank. Asfir armor is designed to survive the most punishing off-road environments while maintaining the clearance you need for technical crawling.
The Problem & The Solution:The Pain: The 4XE’s specialized hybrid components are incredibly expensive to repair if damaged by a jagged rock. Factory plates are often thin and offer limited coverage for the transfer case and fuel tank.
The Asfir Solution: Our 100% Bolt-On system uses heavy-duty aluminum that is significantly stronger than OEM plates but lightweight enough to preserve your electric-only range.
Key Features: The 4XE Armor System
Not a generic JL kit. This system is specifically clearanced for the unique routing and components of the Plug-in Hybrid model.
Mounts directly to existing factory chassis points. No drilling, cutting, or welding required, making it a perfect DIY upgrade.
Integrated ribs in stress-prone zones ensure the plates won't deform or flex under the weight of the vehicle during a strike.
Built-in slots manage airflow to reduce heat buildup around the transmission while allowing mud, water, and debris to escape easily.
Zinc-coated steel mounting brackets and high-grade aluminum prevent rust, even in harsh salted-road environments.
The fuel tank skid is designed to mount securely over the factory plate for double-layered protection without losing clearance.
Superior Strength-to-Weight RatioWeight is a critical factor for the 4XE. Steel kits can negatively impact your MPGe and suspension performance. Our 61 lb (28 kg) kit provides heavy-duty armor while keeping your Jeep agile and efficient on and off the pavement.

"The fitment on my 4XE was perfect. I was worried about the extra weight affecting my battery range, but these aluminum skids are so light I didn't notice a difference. I've already dragged the fuel tank skid over some ledge drops and it held up beautifully with just a few surface scratches. Peace of mind for the expensive hybrid tech is worth every penny."

No. This specific kit is engineered exclusively for the Wrangler JL 4XE PHEV. The hybrid battery and fuel tank layout on the 4XE are unique, requiring these specialized mounting points and clearances.
Because we use 1/4" aluminum rather than steel, the total weight is only 61 lbs. For a vehicle the size of a Wrangler, this weight is negligible and will not noticeably impact your EV range or fuel economy.
No. The Asfir Fuel Tank Skid is designed as a "slip-over" or "mount-over" plate. It installs directly over the existing factory shield, providing a heavy-duty outer shell without the need to drop your tank or remove OEM protection.
No. This is a 100% bolt-on system. It uses existing holes in the chassis and factory crossmembers. It can be installed with basic hand tools in your driveway.
Yes. The engine and transmission skid plate includes access ports and drain holes designed to allow for routine maintenance without removing the entire protection system.

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
