68RFE Stage 4 Billet Multi-Disc Torque Converter

The RevMax 68RFE Stage 4 Billet Multi Disc Torque Converter is engineered to provide a superior upgrade over stock or full-blown sled pulling converters for Dodge Cummins 6.7L trucks model years 2007.5 through 2023. Each RevMax diesel performance converter is custom-made to precise specifications, ensuring that stall speeds and efficiencies are perfectly matched to your specific truck's needs. This ensures a tailor-made unit, not a one-size-fits-all solution, regardless of whether your truck is stock or heavily modified. This Stage 4 converter is ideal for mildly modified engines, those who tow heavy loads, or drivers who wish to avoid the firm shifting characteristics of a Stage 5 triple disc converter. A key feature is RevMax's PATENTED torque converter stator sprag retainer, a unique technology that enhances performance and durability. Many users report that the multi-disc converter offers a smoothness comparable to original stock single-disc units. RevMax recommends upgrading to their Stage 5 converter if you regularly tow over 10,000 lbs or produce more than 550 horsepower. The Stage 4 features a CNC-machined billet one-piece front cover, high-performance Raybestos or Alto lockup frictions, a billet bearing cap with the patented sprag retainer, and a dual Torrington bearing stator design. It also includes a 4140 flanged impeller hub, a 4140 hardened turbine hub, furnace brazed impeller, and a TIG-welded brazed turbine. The converter is assembled with precision internal clearances for increased efficiency and performance, fully pressurized and leak tested, and high-speed balanced to under 5 grams with runout tolerances of less than .005.
