triple disc torque converter for the 2007-Current 68RFE equipped6.7L
Cummins is manufactured and assembled at SunCoast. Boasting
more than 3.4x the lockup clutch surface apply area over stock
(8.7" vs. 29.7") and distributing the load over
three separate surface apply areas, SunCoast's triple disc
converters are sure to put all of the power to the ground.
Starting with a solid chunk of steel, the cover is machined
to exact specifications. Utilizing SunCoast's 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.
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, as well as wear and
tear. The turbine assembly is TIG reinforced and heat-treated.
This exponentially increases its lifespan under harsh conditions.
Stall on this model is approximately 2000 RPM, and much more
efficient at energy transfer than the factory offering.
