Smittybilt Aluminum Inner Fender Liners — Finish Your JK Build With Protection That Shows

If you’ve upgraded your fenders or gone with high-clearance flares, you might be left with exposed wheel wells, messy wiring, or debris buildup. The Smittybilt Aluminum Inner Fender Liners give your Jeep JK or JKU a clean, armored look while protecting critical components from mud, rocks, and trail abuse.

These aren’t just covers—they’re precision-cut, black powder-coated aluminum panels designed to bolt directly into your wheel wells. Available for both the front and rear, they complete your fender setup with form, function, and durability that stands up to real off-road use.

Key Features & Benefits:

  • 🛡 Trail-Ready Protection — Shields engine bay and inner body panels from rocks, mud, and debris kicked up during off-road driving.
