JL Aluminum Rear Inner Fender Liner 

The Details

The factory black plastic "splash guards" you'll find in the wheel openings of your JL can leave a bit to be desired. Our new rear inner fender liners are designed to be installed as a stand-alone item, or compatible with our JL Rear High Line Fender Flares.

Our rear fender liners are laser cut in house from 0.09" thick 5052 Aluminum - which means they are 30% thicker than most 0.06" (16 Gauge) liners on the market, offering a bit more rigidity.

Quick accessibility to is possible thanks to 1/4 turn "dzus" fasteners.

Picture above shows inner fender liner installed alongside our JL rear fender delete. Rear fender delete is sold separately and not included.

Initial installation requires a quick bolt together assembly, and all required hardware is included. Installation requires ZERO drilling, but thanks to the rigidity of the panels and mounting locations on the body, these are entirely body mounted and do not require any fasteners or brackets to be tied into the frame rails of your JL; allowing your body mounts to flex properly without putting any load on your fender liners.

Shock Compatibility

We have been collecting 3D scan data from multiple Jeeps over the past couple of years. This has allowed to CAD design these rear inner fender liners to fit with shocks from factory to aftermarket big body shocks with multiple bypasses with reservoirs; using factory mounts or even the relocated and extended shock/coilover mounts from Rock Crawler Suspension. The short of list of compatible shocks include factory, ADS, Bilstein, King, Falcon, Fox, and Rock Krawler/RRD Shocks. There are always new shock configurations coming out for the ever popular JL platform, so if you have any questions don't hesitate to reach out to us and ask if another new option fits!

4xE Compatibility

The Jeep Wrangler 4xE has additional lines on the rear passenger side leading to the evap canister just in front of the tail lamp; and these extra components are routed through the wheel well where this liner is installed. We have confirmed with a test fit that these DO work without modification on the 4xE PHEV models!

Axle Compatibility: Rubicon vs Sport Axles

Above: A "Willys" trim JL flexing out with the rear inners installed. This JL is equipped with the narrow JL "Sport" axles, and wheel spacers. Some trimming may be required with narrow/Non-Rubicon axles in applications with little to no lift, due to the narrow axle width.

These are designed for maximum up-travel, however they are designed with Rubicon width tires/wheels in mind. If you are running JL "Sport"/Non-Rubicon width axles, either additional offset or some trimming may be required to clear the rear tires at full stuff.

If you are running Rubicon width or even wider axles, clearance is typically increased between the tire and inner fender liner, and should result in no rubbing and no modifications required.
