ALUMINUM DIRECT DRUM ASSY, (7075 BILLET) W/SUPER SPRAG, USE W/ 1.125" MAIN SHAFT (BARE - NO CLUTCHES/STEELS/PISTON)

The Coan Racing CCP‑0228662G Aluminum Direct Drum Assembly is a precisely engineered performance component machined from premium 7075 billet aluminum, tailored for use with a 1.125″ main shaft. Equipped with Coan’s rugged “Super Sprag,” this core is built to handle intense one-way engagement under high-load conditions, but is shipped bare, allowing builders the flexibility to install their own clutch pack, steels, and piston for a customized setup. The lightweight billet aluminum construction dramatically reduces rotating mass, enhancing throttle response and shift speed, while maintaining the strength necessary for demanding drag or circuit applications.

CNC-crafted to exacting tolerances, the CCP‑0228662G offers a direct-fit solution that blends adaptable build options with race-grade durability, making it an excellent choice for serious transmission builders aiming for both performance and flexibility in their Turbo 400 transmission.
