XLT Aluminum FWD Drum w/ Super Shaft (TH Spline)

XLT ALUMINUM FWD DRUM W/ SUPER SHAFT (TH SPLINE)

The Coan Racing CCP-0228603A 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 Coan's robust Super 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-0228603A delivers a durable, performance-focused upgrade for serious builders looking to increase drivetrain strength, reliability, and responsiveness in high-power TH400 setups.
