The Jeep Wrangler JL 4xe is one of the most interesting vehicles in the current lineup — a plug-in hybrid that delivers electric-only off-road capability, improved fuel economy, and a unique set of ownership advantages. But 4xe ownership also introduces some specific considerations for accessories and upgrades that differ from conventional JL Wranglers. This guide covers the best accessories for 4xe owners and what to be aware of before modifying.
What Makes the 4xe Different from a Standard JL
The 4xe uses a 2.0L turbocharged four-cylinder paired with two electric motors and a 17-kWh lithium-ion battery pack. The battery sits low in the frame, lowering the center of gravity compared to the 3.6L Pentastar JL — a genuine handling advantage. However, it also means the ground clearance under the battery management components is slightly reduced, making skid plate protection more important. The 4xe also weighs approximately 600 pounds more than a comparable Pentastar JL.
Lift Kits for the 4xe
Not all JL lift kits are compatible with the 4xe. The battery management components and unique driveline angles require kits specifically engineered for the 4xe architecture. TeraFlex, EVO Manufacturing, and Mopar all produce 4xe-specific lift kits. Attempting to install a non-4xe JL kit can cause clearance issues with battery components and driveline geometry problems. Always verify 4xe compatibility before purchasing any suspension components.
EVO Manufacturing’s 4xe lift systems are widely regarded as the most thoroughly engineered for the platform, with specific hardware for the 4xe’s battery location and modified driveshaft angles. Their 2.5-inch and 3.5-inch kits are the most popular choices.
Skid Plate Priority
The 4xe’s battery management components and charging inlet hardware sit below the floor — making comprehensive skid plate coverage particularly important. AEV produces a full belly skid system specifically engineered for the 4xe that covers the battery tray perimeter in addition to the conventional engine, transfer case, and fuel tank areas. This is a high-priority upgrade for any 4xe that sees trail use.
Charging Accessories
One of the most underutilized 4xe features is the onboard charging capability. The 4xe can power external 120V accessories at up to 5.4 kW — effectively acting as a generator. This makes it an outstanding camping vehicle. Accessories worth adding include weather-sealed power strips designed for outdoor use, compatible inverter hookup cables, and portable refrigerator/freezer units that can run from the 4xe’s power output during camp stays.
Level 2 charging cables and adapters are practical additions for 4xe owners who travel frequently and want faster charging at hotels and trailheads. The factory charging cable handles Level 1 (120V) charging; a compatible Level 2 adapter enables 240V charging where available for significantly faster charge times.
Roof Rack and Storage
The 4xe’s weight penalty makes roof-mounted weight a more significant handling consideration than on lighter Wranglers. Low-profile, lightweight aluminum rack systems from Gobi Racks or Rhino-Rack are better choices than heavy steel options. Keep roof-mounted gear weight under 100 pounds and prioritize it for light items — recovery boards, tarps, and spare wheel assemblies are appropriate; heavy tool boxes and large Jerry can arrays are better positioned lower in the vehicle.
Electronics and Monitoring
The 4xe’s hybrid system generates useful data that most owners underutilize. Aftermarket OBD-II adapters paired with dedicated 4xe monitoring apps (several exist specifically for the JL 4xe) provide real-time battery state-of-charge data, motor output metrics, and charging efficiency information. This data is valuable for understanding how to maximize the 4xe’s electric range in daily driving and on the trail.
Final Thoughts
The 4xe is a well-conceived trail vehicle that benefits from thoughtful accessory choices. The key principle: verify 4xe compatibility on every suspension and underbody modification, prioritize battery protection, and take advantage of the unique charging capability that makes the 4xe an outstanding base camp vehicle. The aftermarket for the 4xe is growing rapidly and specific well-engineered solutions now exist for every major upgrade category.
