Rear Valance Aero Foil Kit
for Ford Mustang GT 2018-23
Manufactured by ROUSH® Performance #422085
Ready to race, or just show off the performance capabilities of the 2018+ Mustang? Add a ROUSH Rear Valance Aero Foil Kit, designed to work with the factory quad-tip GT valance!
Designed utilising 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. Couple these foils with the ROUSH Lower High-Flow Opening (P/N 422081) and 3-Piece Chin Spoiler and Wheel Shroud Kit (P/N 422082) for the complete lower aero package!
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 moUlded 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. Easy installation means no trimming or painting is required (drilling for mounting is required). All required parts are included, such as hardware, templates, and detailed instructions.
Features:
- Fits 2018-23 Mustang GT - will NOT fit EcoBoost or GT350.
- Add to the factory rear valance for an aggressive look inspired by racing.
- Made from injection-molded TPO (Thermoplastic Poly Olefin) with a black stipple finish.
- Offers OEM look, long-lasting durability, and flexibility.
- Lightweight and impact resistant.
- Designed with OEM CAD data to ensure precise fit.
