Sonnax 10-clutch drum 28756-01 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 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
• Accepts 24- or 12-tooth steels
• Use with Sonnax clutch piston 28765-05 and a 10-clutch hub with lightening holes 28304-01 or without 28304-02.
