.Sonnax Powerglide Servo Piston & Cover Kit 28821-08K

Description

Dual-seal design, PTFE sealing ring style, Non-anodized
GM Powerglides used for drag racing generate higher line pressure than the OE servo piston can withstand. At pressures over 200 psi, the OE piston can crack, resulting in transmission failure. Sonnax servo piston and cover kit 28821-08K improves transmission performance and durability under high-pressure conditions.
High-strength billet aluminum piston also features a rounded profile for better stress distribution
Dual PTFE seals improve sealing, are low-friction and interchangeable with the OE cast aluminum seal ring
Lightweight, billet aluminum cover replaces heavy, cast-iron OE cover
Easy to install, no case modifications required
