Product Description

The factory stamped-steel flexplate on 1989-2007 Dodge Ram 2500/3500 trucks with the 5.9L Cummins is a known weak point once power levels climb past stock. Under the added torque of towing, performance tuning, or an upgraded torque converter, that thin factory plate can crack or shatter outright - often at the worst possible time. ATS built this billet flexplate specifically to eliminate that failure point.

Machined from solid billet steel and SFI approved to race-application standards, this flexplate is engineered to handle the stress that high-horsepower Cummins builds put on the drivetrain, transferring power to the wheels without the flex and fatigue that dooms the stock part. It's a common companion upgrade for anyone stepping up to a triple-disc or higher-capacity aftermarket torque converter, where the added clamping force accelerates wear on a factory flexplate.

One fitment detail matters here: 1989-1993 trucks require a flat-back, non-lock-up style torque converter to pair with this flexplate rather than the factory lock-up unit. Later 1994-and-up applications work with both stock and aftermarket converters. Confirm your truck's converter style before ordering to avoid a compatibility mismatch at install.
