The Coan Racing COA‑22813B Billet Steel Forward Drum with "Super Shaft" Alloy Input Shaft is a heavy-duty, precision-engineered assembly designed for high-performance and race-ready Turbo Hydramatic 400 transmissions. Weighing in at approximately 9.75 lbs, this billet steel forward drum integrates Coan’s "Super Shaft" alloy input shaft, offering a substantial strength and durability upgrade over OEM components. Built in the USA, the part is highly regarded for its robust construction, capable of enduring extreme torque loads while maintaining superb structural integrity, essential for serious street/strip and bracket racing applications.
