Upgrade one of the most critical failure points in the 47RH, 47RE, and 48RE transmissions with the RevMax Billet Input Shaft - 23 Spline One-Piece Design - 478-500-1 for 1993–2007 Dodge Ram 2500 and 3500 trucks equipped with the 5.9L Cummins. Factory input shafts are known to fail under high torque loads, aggressive launches, and heavy towing conditions, especially when paired with upgraded torque converters and increased horsepower. This heavy-duty RevMax shaft is machined from 300M billet steel in a one-piece design that integrates the input shaft and clutch hub for maximum strength and reliability. Engineered to withstand extreme torque, it resists twisting and snapping while improving oil flow to the direct clutch pack for better lubrication and engagement. Ideal for high-performance builds, towing applications, and transmission upgrades, this shaft is a must-have for any serious Cummins drivetrain build.

• A must for any high horsepower or heavy hauling application.
• This shaft resists snapping from boosted launches and heavy loads.
