Sun Coast M3GA-4C-978A Billet 4C Snap Ring Retainer

The Sun Coast M3GA-4C-978A Billet 4C Snap Ring Retainer is a massive upgrade from the stock 4C snap ring retainer in the 68RFE transmission in your 2007.5-2018 Dodge 6.7L Diesel. The factory 4C snap ring in the 68RFE is notorious for blowing out from the center support. This spring-loaded component essentially encapsulates the snap ring, preventing any blowouts from happening again.
