4C Piston Return Spring Retainer Assembly

Complete drop-in billet steel 4C clutch spring retainer with springs. Replaces Mopar #4799527AB. 

Goerend Difference:

Our 4C return spring retainer assembly utilizes a billet steel upper and lower retainer. The upper retainer of this assembly captures the 4C snap ring, ensuring that the snap ring will not be displaced from its groove and cause clutch failure.

Unlike other aftermarket retainer assemblies, our upper and lower retainers are bolted together. This is done to prevent each retainer from rotating against each other, rolling its springs over.

US Patent 12565915-B2

The Goerend 4C Piston Return Spring Retainer Assembly is a patented upgrade designed to eliminate the common weaknesses found in OEM and traditional aftermarket 4C clutch spring assemblies. Engineered for durability and consistent clutch operation, this assembly improves clutch release performance while preventing the failures that can occur under high-load applications.

Unlike factory designs that rely solely on a snap ring, the Goerend assembly uses precision-machined upper and lower spring retainers secured together with shoulder bolts. This design prevents the retainers from rotating relative to one another while allowing controlled axial movement during clutch apply and release.

Each return spring is captured in dedicated machined pockets on both retainers, keeping every spring properly aligned throughout operation. By eliminating spring rollover and maintaining consistent spring positioning, the assembly delivers reliable piston return and proper clutch disengagement.

The upper retainer also features an integrated snap ring retention shoulder that helps prevent the retaining ring from walking out of its groove—a common failure point in OEM assemblies. This added security provides greater reliability in high-performance and heavy-duty applications.

Whether you're building a performance transmission or increasing the reliability of a work truck, the Goerend 4C Piston Return Spring Retainer Assembly provides a stronger, more dependable solution than factory components.
