Sonnax® - High Performance Automatic Transmission Clutch Apply Piston Kit

High Performance Automatic Transmission Clutch Apply Piston Kit by Sonnax®. High Capacity 4-5-6. Includes: Backing Plate, Apply Plate, Piston Dam, Apply Piston. Sonnax high capacity 4-5-6 clutch apply piston kit features a modified OE clutch apply piston and piston dam that are used in conjunction with a specially-designed toothed apply plate closest to the piston. The Sonnax toothed apply plate increases surface area between the apply piston and first friction plate resulting in more even distribution of apply force to clutch plates and allows a friction plate to run against the apply plate. By eliminating the OE waved plate and adding one additional OE thickness friction, 4-5-6 clutch capacity is increased by 17% resulting in a 4-5-6 clutch pack that can handle modified engines with increased power output.
