These durable plastic inner fender liners simplify the process of installing aftermarket fender flares on your 2018+ Jeep Wrangler JL. The biggest headache when installing aftermarket fender flares on your Jeep is trying to get the stock plastic inner fender liners to fit correctly. Since the stock pieces are designed to integrate with the OE flares, they have to be tediously cut and modified for use with aftermarket flares, and the result is often less than satisfactory. That's why we designed these replacement inner fender liners to fit perfectly, right out of the box, with virtually any aftermarket fender flare without modification. They're proudly manufactured in the USA from durable ABS plastic, using a thermo-forming process with precision engineered tooling for an exact fit. The kit comes complete with the rear inner fender liners (driver side rear, passenger side rear) as well as installation hardware and detailed instructions. Installation is a simple bolt-on process, with no drilling or cutting required. Visit our website for helpful installation videos for this product.
