Product details
Upgrade your 2021–2025+ Tesla Model S with the Yeslak Carbon Fiber Rear Diffuser Replacement, designed for enthusiasts who demand peak performance, cutting-edge aerodynamics, and a head-turning sporty look. This premium rear diffuser is a full carbon fiber replacement for the OEM bumper, merging luxury design with race-inspired engineering.
Premium Carbon Fiber Construction
Built from Real Pre-preg (Dry) Carbon Fiber that offers superior strength, lighter weight, and better uniformity than wet carbon fiber, which is really heavy, this diffuser offers both Matte and Glossy finish options for a bold, high-end appearance.
Aerodynamic Performance You Can Feel
Engineered for optimal airflow, the diffuser reduces drag and increases rear-end downforce, improving stability, handling, and efficiency at higher speeds. Pair it with Yeslak’s matching front lip, side skirts, and spoiler for a complete aero kit that transforms your Model S into a true performance machine.
Seamless Factory Fitment
Designed as a direct OEM replacement, the Yeslak rear diffuser integrates flawlessly with your Tesla Model S for a factory-style look that feels custom. The carbon fiber weave delivers a striking visual upgrade, enhancing your car’s sporty, luxury aesthetic.
