Using the patented Sonnax 10-clutch drum system, the drum and piston accept 10 frictions and 10 special Kolene¬ steels, increasing lockup surface to allow significantly more torque than modified OE drums.The drum is machined to accept a Koyo¬ thrust bearing and can be used without any modification to the pump assembly.

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