This Wheel Well Liner kit serves a couple of functions. First, it replaces the FFR front splash guards that are supposed to protect the headlight assemblies. Those parts don’t really fit properly to do the job they were intended to do. Second, these liners protect the bottom side of your hood from rocks and debris being thrown up against the bottom of the hood, which will result in cracks and chips showing up in the paint on the top of your hood over time. This kit comes with the plastic liners with high quality rubber bulb seal to seal between the body and liner, aluminum mounting brackets and mounting hardware.
