5th Gen 6.7L Cummins Transmission

Heavy-Duty Transmissions, Converters & Upgrades

Handle massive torque output, eliminate slippage, and ensure reliable power transfer under heavy towing conditions with heavy-duty transmission components for your Ram 2500 or 3500. The factory 68RFE and Aisin transmissions are notorious for struggling under increased tuning power or heavy loads, often resulting in clutch slip or limp mode. Upgrade your 5th Gen 6.7L Cummins drivetrain with heavy-duty torque converters, robust clutch kits, valve bodies, and complete built transmissions engineered to handle extreme torque without compromise.
