Fiberwerx's 2014-2018 GMC Sierra fenders are a perfect addition to trucks with lift kits or long travel kits. These are simple bolt on fiberglass fenders.

The holes are pre-marked so you will have to drill your own holes in the fiberglass. The wheel well is larger then factory so the factory wheel well liners will not work. If you would like wheel well liners, you will have to build your own. We have a front valance option available that is able to re-use the factory fog lights or use light pods of your choice! These parts will come as a white gelcoat, they are not primed or painted.
