XLT ALUMINUM FWD DRUM W/ 300M SHAFT (TH SPLINE), 3.75 LBS

The Coan Racing CCP‑0228603 XLT Aluminum Forward Drum is a race-engineered component designed to dramatically enhance the performance of a Turbo Hydramatic 400 transmission. Meticulously machined from lightweight billet aluminum, this forward drum is paired with a robust 300M alloy input shaft (TH spline). This assembly offers a significant weight reduction over heavier OEM cast iron drums, minimizing rotating mass for quicker throttle response and faster shift recovery. The oversized spline interface between the shaft and drum mitigates spline fatigue and failure commonly encountered in high-stress racing environments.

By combining premium materials and precision craftsmanship, the CCP‑0228603 delivers a durable, performance-focused upgrade for serious builders looking to increase drivetrain strength, reliability, and responsiveness in high-power TH400 setups.
