28756-25K Smart-Tech Drum

Smart-Tech 10-clutch drum kit features a 35% larger piston that maximizes both engaging and holding capacity of the 10-clutch system. 10-clutch drum kits are optimized for Powerglide performance applications. The drum and piston accept 10 .060″ frictions and 10 .060″ thick steels, increasing lockup surface to allow significantly more torque than modified OE drums. Smart-Tech components give you the option to reduce line pressure for greater efficiency, or drop to seven frictions for less parasitic drag and improved heat dissipation while retaining 10-clutch capacity.   35% More apply area Use with your choice of frictions and steels Patented drum, hub and piston system improves clutch capacity for maximum durability High-strength drum with reduced rotating mass improves on-track acceleration 6061 Forged piston will not crack like cast pistons Forged chromoly clutch hub guarantees your power makes it to the wheels Thrust bearing used between pump and drum
