The Sun Coast 68RFE-46-3D Triple Disc Torque Converter for your 2007.5-2012 Dodge 6.7L Cummins is a redesigned  converter for your the 68RFE. Featuring a completely new stator, turbine, turbine hub, billet piston, our SCD three disk clutch plates and a billet front cover, this converter has no limits! Boasting more than 3.4x the lockup clutch surface apply area over stock (8.7” vs. 29.7”) and distributing the load over 3 separate surface apply areas, our triple disc converters are sure to put ALL of your power to the ground. 

Starting with a solid chunk of steel, the cover is machined to exact specifications and ends up being nearly double the thickness of the weak factory cover. Utilizing our exclusive trapezoidal teeth design, the lockup portion of the converter is seamlessly integrated into the cover, eliminating a weak point and common source of chatter. An upgraded billet lockup apply piston is able to transfer a much higher pressure to the lockup clutch without sacrificing durability. Instead of the factory style plastic stator cap/thrust spacer, SunCoast utilizes a metal Torrington roller style bearing which is better suited to take the heat and abuse you can throw at it. The turbine assembly is TIG reinforced and heat-treated; exponentially increasing it’s lifespan under harsh conditions.

Stall on this model is approximately 1900-2000 RPM, yet much more efficient at energy transfer than the factory offering.
