This Powerglide 10-clutch drum, hub and piston kit 28756-15K includes the three essential components for building a 10-clutch drum assembly.
Using the patented Sonnax 10-clutch drum system, the drum and piston accept 10 frictions and 10 steels, increasing lockup surface to allow significantly more torque than modified OE drums.
The drum features a piston bore that is .060" deeper for greater piston travel than was available from Sonnax 10-clutch drum 28755-01 (discontinued).
- Drum holds 10 .060" frictions and 10 .060" thick steels
- Excess material removed from high-strength, cast steel drum to reduce rotating mass
- 6061 Forged aluminum piston will not crack at high operating pressure like cast pistons
- Forged chromoly steel clutch hub
- Thrust bearing used between pump and drum
- Patent No. 6,920,970
- Patent No. 7,204,357
