NEW! Smart-Tech® High Capacity Input Shaft & Piston Kit

Delivering an unrivaled combination of 20% increased direct clutch torque capacity and maximum durability from our existing one-piece 300M input shaft design, the new Sonnax Smart-Tech high capacity input shaft and piston kit 22121B-02K is now available for Chrysler 47RE, 47RH and 48RE units.

Featuring a hub with longer direct clutch splines and a thinner billet aluminum direct piston, this kit is specially engineered to avoid common problems that many other aftermarket modifications cause. The key is adding one extra friction plate, while maintaining the OE-thickness backing plate, retaining ring and clutch clearances for optimal results.
