Powerglide 10-Clutch Steel Complete Drum Kit.

These Powerglide drum kits are configured to use high performance frictions and steels, which significantly increase lock-up surface area and allow the drum to hold more torque. The drum is constructed from a high-strength cast steel and has had excess material removed to reduce rotating mass. Oil holes have been added to allow fluid to escape the drum and permit the piston to engage quicker. A standard needle bearing stepped into the front side reduces friction and drag while the high strength, forged steel clutch hub is built extra tall to accommodate the additional clutch plates.
