Sonnax 10-clutch drum with bearing 28756-08 is optimized for Powerglide performance applications. 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 is machined to accept a thrust bearing and can be used without any modification to the pump assembly.

Drum holds 10 .060" frictions and 10 .060" thick steels
Excess material removed from high-strength, cast steel drum to reduce rotating mass
Accepts 24- or 12-tooth steels
Thrust bearing used between pump and drum
Use with Sonnax clutch piston 28765-05 and a 10-clutch hub with lightening holes 28304-01 or without 28304-02.

The drum features a piston bore that is .060" deeper for greater piston travel than was available from Sonnax 10-clutch drum 28755-08 (discontinued).
