For those who eat, sleep and breathe off-roading, ARIES fender flares show off your off-road tires better than factory flares, and they feature strong, lightweight aluminum construction to easily stand up to the elements. These inner fender liners are designed to mount with ARIES Jeep JK fender flares #1500201 and provide ultimate protection for your engine compartment against mud, water and road debris. ARIES Jeep inner fender liners are constructed from welded aluminum to not only be lightweight and rust-free, but also to offer better strength than the plastic factory fender liners. They are also covered in a highly durable carbide black powder coat finish for maximum corrosion protection. ARIES inner fender liners install securely in conjunction with ARIES fender flares and include all necessary hardware for a complete installation (some drilling and rivet nut installation required).
