The Sonnax 10-clutch system increases lockup surface in GM Powerglides for significantly more torque capacity than modified OE drums. The drum kit includes 10 .060" frictions and 10 .060" thick, 12-lug steels, increasing lockup surface to allow significantly more torque than modified OE drums.
Sonnax 10-clutch drum kit 28756-01K is a complete drum kit that includes all high-clutch-related components, including a pre-installed, PTFE-coated bushing.

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
