Detailed Description:

The 68RFE transmission, used in Dodge Ram trucks with the 6.7L Cummins engine, is a robust six-speed unit designed to manage significant power and torque. Despite its strength, it can face issues under heavy loads or with aftermarket modifications. The SunCoast Guardian Torque Converter and its associated components provide practical solutions to these problems, enhancing the transmission's reliability and performance.

The SunCoast Guardian Torque Converter is built for durability and efficiency. It features carbon-graphitic clutches and hardened turbine splines to ensure dependable operation under demanding conditions. This converter is particularly well-suited for towing and hauling but is not intended for racing applications.

The Sonnax Smart Tech Overdrive Drum Assembly addresses weaknesses in the factory overdrive clutch. It offers a 16% increase in clutch surface area and a 28% boost in clutch steel mass, improving heat dissipation and reducing the risk of clutch failure. Additionally, the top bolt-on plate helps prevent clutch pack flexing and distortion.

The Suncoast Ducenti Valve Body is designed to resolve hydraulic circuit issues with its 200psi shift calibration. It includes a new pump half, TCC limit valve, and billet accumulator pistons, providing a comprehensive drop-in solution that does not require additional tuning.

The SunCoast Zero Cavitation Filter Kit replaces the factory filter system, which has had issues with pressure relief valves and cavitation. This kit uses a Torqueflite filter to prevent pump cavitation and allows for a higher fluid volume, thereby improving overall transmission performance.

Other components include the 68RFE Thrust Washer and Bearing Kits, essential for maintaining internal transmission integrity, and the 68RFE Complete Gasket and Sealing Kit, which ensures a leak-free and reliable installation.

With components rated for up to 450 horsepower, these upgrades are ideal for those seeking improved performance and reliability from their 68RFE transmission, whether for towing, hauling, or daily driving.
