Upgrade Your 6.7L Cummins with Unmatched Strength and Reliability

Take your 2019-2026 RAM 6.7L Cummins to the next level with the SunCoast Category 1 450HP 68RFE Transmission. Whether you're towing, hauling, or running performance upgrades, this transmission is built to handle the extra load with confidence. The factory 68RFE has known weaknesses, especially under high torque conditions, but SunCoast has addressed each issue with precision engineering and heavy-duty billet components. This transmission delivers smoother, stronger shifts, extended longevity, and improved power transfer, giving you the peace of mind to push your truck to its full potential.

Reinforced with Smart Tech Engineering for Superior Performance

The SunCoast 68RFE transmission is designed to overcome the common failure points of the stock unit, ensuring maximum durability and reliability. The Sonnax Smart Tech Overdrive Drum Assembly increases clutch surface area by 16%, significantly reducing heat buildup and improving performance under heavy loads. The billet 2C piston enhances clutch engagement, while the Ducenti Pro-Loc 200 PSI Shift Calibration Kit optimizes hydraulic efficiency for firm, precise shifts. With a zero cavitation filter kit to prevent pump starvation and a new OEM Mopar solenoid pack, this transmission is engineered to run cooler, shift smoother, and last longer than stock. Plus, its drop-in design ensures easy installation, making it the ultimate upgrade for your Cummins-powered Ram.

Heavy-Duty Torque Converter for Maximum Power Delivery

The included SunCoast billet torque converter takes efficiency and durability to a whole new level. Unlike the weak factory unit, this converter features triple-disc technology for stronger lockup, better heat dissipation, and improved torque multiplication. Whether you're towing up steep grades or launching under load, this converter ensures seamless power transfer and reduced slippage, maximizing your truck’s performance. Paired with the SFI-certified billet flexplate, this setup eliminates flex and ensures smooth engagement for long-lasting reliability under extreme conditions.
