Sonnax® - High Performance Clutch Apply Piston

High Performance Clutch Apply Piston by Sonnax®. 1-2-3-4. Material: Aluminum. The 1-2-3-4 pistons commonly crack due to cantilevered stress on the cast material. The OE part has been through several revisions in an attempt to correct this, but all OE versions are still chronically known to crack. Sonnax heavy duty 1-2-3-4 piston is made from stronger, billet aluminum and has superior design refinements that add additional strength to prevent breakage and deliver maximum performance throughout the life of the transmission.

Features

• Use with stock clutches and one additional friction plate
• Solid backing plate design outperforms OE and aftermarket plates
• Toothed apply plate eliminates waved plate and allows one additional friction plate
