Fits select 1994-2004 Dodge Ram 2500 and 3500 (5.9L).

The South Bend Clutch NV4500 1.375-inch Input Shaft Upgrade Kit is a critical modification for high-torque 5.9L Cummins diesel trucks. The factory input shaft in the NV4500 transmission is often a point of failure when engine output is increased or when hauling heavy loads. This kit replaces the standard factory shaft with a significantly more robust 1.375-inch diameter version, increasing the shear strength and overall durability of your drivetrain.

  • Designed specifically for the NV4500 5-speed manual transmission
  • Upgraded 1.375-inch shaft diameter for superior torque handling
  • Replaces original smaller input shaft to support heavy-duty diesel clutch applications
  • Engineered for high-performance tuning and heavy towing environments
