SunCoast M3GA 4C Snap Ring Retainer

Description
The SunCoast M3GA 4C Snap Ring Retainer is designed to strengthen one of the most common failure points in the 68RFE automatic transmission. Under heavy towing, high line pressure, and increased horsepower, the factory 4C snap ring can flex or fail, leading to clutch pack damage and transmission failure. This upgraded retainer helps provide improved clutch retention and increased durability for demanding diesel applications.
Built for towing, performance, racing, and heavy-duty use, the SunCoast M3GA Snap Ring Retainer is a valuable upgrade for both stock and built 68RFE transmissions.
