Each splitter fits underneath the rear valance to create an aggressive styling line with the road.Our splitter kit is made from high-strength TPO for long lasting durability. The plastic is molded with high-pressure injection, the same process used by the automotive manufactures.

Installation takes only minutes, and there is no trimming needed, as there would be with our competitors products. All required parts are included.
