NEW! Powerglide Servo Kits

Powerglide supported servo master kit 28821 20k

For Powerglide racing enthusiasts, Sonnax now offers a top-of-the-line servo solution that fills the bore from soup to nuts: supported servo master kit 28821-20K

The foundation of the kit is a unique supported pin and cover design to ensure the piston will apply and release without binding. The kit also includes Sonnax's new race-calibrated return spring 28133-HD to prevent "mystery" band failures at high line pressures. 

A more basic supported servo pin and cover kit 28821-19K also is available to mix and match with OE or aftermarket servo pistons.
