Front and Rear Aluminum Inner Fender Liners for Wrangler JK 2007-2018

Finish the look of your high-clearance build and let that hot JK engine bay breathe.

Vented Aluminum Inner Fender Liners for Jeep Wrangler JK (JK/JKU)

If you have installed aftermarket flat fenders or chopped your stock flares, you know the ugly result. You are left staring at exposed frame rails, messy wiring harnesses, and the engine block. These aluminum inner liners clean up that wheel well gap for a finished, custom look. Because the JK chassis remained consistent from 2007 to 2018, these fit both the early 3.8L and later 3.6L Pentastar models. They provide a shield against rocks kicking up into your serpentine belt or alternator while allowing engine heat to escape.

Why You Need This Upgrade

• Heat Dissipation: The vented design promotes airflow through the engine bay, helping to lower under-hood temperatures during slow crawls.
• Ultimate Protection: Replaces flimsy stock plastic with durable aluminum to shield vital suspension and engine components from trail debris.
• Customizable Finish: Arrives in a standard black finish but is easily scuffed and painted to match your Jeep's accent colors.
• Clean Aesthetics: Hides the unsightly gap between the frame and the fender that occurs when running high-clearance flares.
