Armor Your High-Voltage Power. Lightweight Aluminum. 100% Bolt-On Security.
Essential Armor for Your Hybrid BatteryThe Asfir 4x4 Rear Battery Protector is a mission-critical upgrade for every Jeep Wrangler JL 4XE Plug-In Hybrid owner. While the 4XE is a beast on the trail, its high-voltage battery sits in a vulnerable position. A single rock strike or "tail-drag" on a steep departure could lead to a catastrophic repair bill.
This shield is crafted from premium 1/8" (3.17 mm) laser-cut aluminum. It provides a rugged barrier against trail obstacles without adding the excessive weight that would negatively impact your electric driving range or payload capacity.
The Hybrid Protection Dilemma:The Pain: The 4XE hybrid battery is extremely expensive to replace ($15,000+) and sits right where rocks tend to hit during technical descents. Most armor is too heavy for hybrid efficiency.
The Asfir Solution: A lightweight 9 lb aluminum shield that features integrated stiffening ribs and a 100% Bolt-On design. It protects your power source while maintaining your range.
Key Features: 4XE Battery Protection
Specifically engineered for the Wrangler JL 4XE PHEV chassis. It hugs the battery tray perfectly to maximize departure angles.
At only 9 lbs, this aluminum shield adds negligible mass, ensuring your electric range and suspension performance remain unaffected.
Uses factory mounting points for a secure, 100% bolt-on assembly. No permanent modifications to your frame or hybrid housing.
Features laser-cut air vents to prevent battery overheating and drain holes to clear mud, water, and trail debris.
Pressed stiffening ribs increase the structural integrity of the 1/8" aluminum, allowing it to withstand high-force impacts.
The aluminum plate is naturally corrosion-resistant, supported by zinc-coated steel brackets for long-term durability in all weather.
Tailored for the Plug-In Hybrid LifestyleWe understand that 4XE owners use their vehicles differently. You want the capability of a Jeep with the efficiency of a hybrid. Asfir’s battery protector ensures that an off-road miscalculation doesn't turn into a total loss. By using lightweight aluminum instead of heavy steel, we keep your center of gravity low and your hybrid system efficient.

"The rear departure angle on the JL is decent, but on the 4XE, that battery tray feels like a target. I installed the Asfir protector in about 30 minutes. It fits incredibly tight to the body. Last weekend I came off a ledge and felt a scrape—checked underneath and the plate did its job perfectly. Worth every penny for the peace of mind."

Precision designed specifically for the rear battery configuration of the Plug-In Hybrid. Fits the following:
2021 - current Jeep Wrangler JL 4XE PHEVEngine: 2.0L Turbo Hybrid
Chassis: 4-Door Models Only
Note: Designed to clear all high-voltage cabling and cooling lines associated with the hybrid battery system.
No. Asfir has integrated ventilation slots specifically designed to maintain airflow around the battery housing, ensuring that your PHEV system stays within its optimal operating temperature during heavy use.
No. This protector is exclusive to the 4XE PHEV model. Non-hybrid Wranglers do not have the rear battery tray that this plate is designed to protect. For standard Wranglers, we recommend the Asfir fuel tank or transfer case skid plates.
Yes. While 1/4" is used for high-impact zones like the transfer case, 1/8" aluminum reinforced with pressed ribs is ideal for the rear battery. It provides excellent protection against sliding over rocks and debris while keeping the weight minimal.
This protector is designed to mount closely to the factory battery tray. Most standard aftermarket bumpers and hitches clear this area without issue. However, if your bumper significantly modifies the rear crossmember or battery mounting area, compatibility may vary.
Yes. The package includes the aluminum skid plate, zinc-coated steel brackets, and all necessary bolts and fasteners for a complete installation.

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

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
