Roush RSH Rear Valances Diffusers - 422085

Ready to race, or just show off the performance capabilities of the 2018-2023 Mustang? Add ROUSH Rear Valance Aero Foil Kit, designed to work with the factory quad-tip GT valance! Designed utilizing techniques used in racing to improve aerodynamic efficiencies, ROUSH Rear Valance Air Foils work to separate the airflow beneath the car, allowing a smaller portion to follow the under-body contours, adjusting rear downforce. Each piece is made from high-strength TPO (thermal plastic olefin) with a black stipple finish, for an OEM look and lasting durability. The plastic is molded with high-pressure injection, the same process used by OE automotive manufactures, which allows for impact resistance and durable flexibility, while remaining lightweight with low density.

Ships Free. Rear Valance Aero Foils for the 2018-2023 GT Mustang are injection-molded for lasting durability & OEM CAD designed for a precise fit. Ready to race?
