The DMS 2 Gallon Fender-Mounted Supercharger Coolant Expansion Tank is designed to substantially increase the coolant capacity of the 2017–2024 Camaro ZL1 intercooler system while maintaining a clean, hidden installation.
Adding 2 gallons of coolant capacity significantly increases the system's thermal mass, helping slow heat soak and maintain more consistent intercooler performance during repeated pulls, spirited driving, drag racing, and track use.
The tank mounts inside the fender, keeping the additional coolant capacity away from engine-bay heat while providing easy access for filling and bleeding through the factory fender opening.
