1994-2007 Ram 2500 & 3500 5.9L Cummins SunCoast Lightweight Reaction Shell

1994-2007 Ram 2500 & 3500 5.9L Cummins SunCoast 48RE Lightweight Reaction Shell Features:

Lightweight Reaction Shell

Weight is always on the mind of any drag racer. Reciprocating mass is one of the most efficient ways to improve the performance of any vehicle. Lighter rotating mass improves an engine's response to throttle input, and it reduces parasitic loss, as well.

This new ultra-light billet reaction shell weighs 30% less than the factory piece and yields itself much stronger. This piece fits both 727 Torqueflights and 47/48 RH/RE transmissions. This piece is perfect for Drag Racers, Sled Pulls, and Max Effort street builds.

Technician's Note: On-diesel applications require the driving of the factory Sun Gear to repitch the splines. This is a common practice and can be done by a technician level of D or higher.
