Description
Unlock the full potential of your 6.7L Cummins with the SunCoast 2200 Stall Triple Disc Converter, engineered specifically for 2007–current RAM trucks equipped with the 68RFE. Designed and built in-house, this converter delivers massive strength, faster response, and dramatically improved power transfer compared to the weak factory unit.
Whether you tow heavy, run larger turbos, or simply want a converter that won’t fail under high load, the SunCoast 3D Converter provides the durability and efficiency needed for serious performance.
Why Choose This Converter?
The factory 68RFE converter suffers from small clutch surface area, weak internal components, and poor heat resistance. SunCoast solves all of these issues with a complete billet redesign:
Triple Disc Lockup — 3.4× More Apply Area
With 29.7 sq. in. of clutch surface (vs. the OEM’s 8.7), lockup is stronger, smoother, and capable of handling big torque without slipping.
2200 Stall for Improved Turbo Spool & Driveability
The optimized 2200 stall speed delivers better off-the-line response and helps light chargers more efficiently, while maintaining excellent towing manners.
Fully Billet, Fully Reinforced Construction
Built from premium materials to handle extreme torque:
CNC-machined billet stators (1800–3000 stall options available)
4140 hardened turbine splines
Billet steel & aluminum pistons
Fully forged billet cover with SunCoast’s exclusive trapezoid lockup teeth
Superior Heat & Load Management
TIG-reinforced and furnace-brazed fins
Metal Torrington bearing replaces weak OEM plastic components
Pressure-tested welds & digitally balanced
Every converter is hand-assembled and machined in-house for unmatched consistency and strength.
