ACS C8 Stingray Rear Diffuser Insert

Elevate your C8 Stingray with the ACS C8 Stingray Rear Diffuser Inserts for better performance and style. Say goodbye to the bland rear valence and add a bold, aggressive look with our cutting-edge diffuser conversion.

Easy to install, this modification requires just four simple holes to be drilled on the unpainted undercarriage pan and is completely reversible.

Not only does the ACS Diffuser enhance the appearance of your vehicle's rear end, it also improves aerodynamics by reducing turbulence and directing fast-moving air away from the undercarriage. Perfect for performance enthusiasts seeking to upgrade their C8 Stingray with both style and performance.


  • Enhance airflow in your C8 Stingray's diffuser tunnels with a linear directional design
  • Boost aerodynamics with reduced turbulence at the rear
  • Reversible mod
  • Painted in Carbon Flash Black for a seamless and stock look or available in select body colors for a bolder appearance

How it's made

Made with precision, the ACS Diffuser Inserts are digitally designed specifically for the C8 Stingray, ensuring a perfect fit with the C8's rear valence. Crafted from PC Composite via injection with a Carbon Flash Black finish to match the Stingray's trim parts. Select body colors are available for an even bolder look.

    Carbon Flash Black:

    CFZ is a black paint finish with a silver metallic flake in the paint. From far it appears as a gloss black finish; however, upon closer inspection a silver metallic flake can be seen inside the paint finish. CFZ matches all C7 Corvette accent pieces on the Corvette including the fender insert, hood insert, front grill, rear diffuser, and more. Carbon Flash Metallic Black is highly recommended by us for any Corvette parts.
