Jeep JK owners, ready to armor up? This is a complete 4-piece set of heavy-duty inner fender liners for both the FRONT and REAR of your 2007-2018 Wrangler JK or JKU (fits Sport, Sahara, Rubicon). They're made from cold-rolled steel with a tough black powder coat to fight rust and look great. They totally replace the flimsy factory plastic liners, giving you way better protection against mud, rocks, and debris getting thrown up into your engine bay and body. The vented design looks cool, helps with heat dissipation, and lets you peek at your suspension. Installation is pretty straightforward with the included hardware, and they provide easy access to your shocks. Keep your Jeep cleaner and better protected on and off the trail with this essential upgrade.
