Upgrade Your Transmission for Maximum Durability

The ATS Heavy Duty Overdrive Clutch Drum is designed to solve common transmission failures in 2007.5-2018 Ram 6.7L Cummins trucks equipped with the 68RFE, 545RFE, 65RFE, or 66RFE transmissions. Built from billet aluminum for extreme strength, this upgraded clutch drum addresses the limitations of the factory overdrive system, which often fails under heavy towing or high-horsepower use. Factory clutch plates are thin and prone to warping, which can lead to heat buildup, slippage, and eventual transmission failure. This kit solves that problem with a taller clutch pack, double-sided clutches, and reinforced steel plates, all working together to improve power handling and heat dissipation. The result? More reliable performance, especially for trucks pushing 600+ horsepower or frequently pulling heavy loads.

Designed for Performance and Longevity

This clutch drum upgrade offers a 16% larger overdrive apply area, which improves shift firmness and control under heavy loads. The clutch pack itself is physically taller, providing 20% more clutch capacity compared to stock components. With 2X thicker steel plates and a bolt-on anchor plate, heat dissipation is improved by 28%, while the risk of clutch flex and distortion is significantly reduced. These design features ensure long-term reliability by keeping heat in check and maintaining proper clutch pack clearance, even under intense use. This kit arrives disassembled and requires assembly, but it’s engineered to be a complete, top-tier solution without needing valve body or pump modifications. Built for those who demand superior strength and dependability, the ATS Heavy Duty Overdrive Clutch Drum keeps your truck on the road and working hard.
