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
