This rivet style fender flare provides extra coverage on trucks with larger wheel and tire packages. Update your vehicle with an awesome, wide-body look while shielding it from road debris. The extra height of the flares is also a great quick fix for covering rust and minor damages on the fender. This distinctive fender flare, available in four-piece sets, is designed to not only add a rugged, off-road look, but also protect the sides of your vehicle from road debris and harsh outdoor elements.

This flare is built to last and is backed by a Limited Lifetime Warranty. Straight from the die, the flare has a satiny finish (standard) that looks great, but is easily prepped and painted for any sort of automotive paint. The flare is also available in a textured finish.
