Description

The USA Standard Gear ZMNV25356MK is an input shaft upgrade kit engineered for the NV4500 manual transmission. This kit is specifically tailored for 1994-2004 Dodge 2500 and 3500 diesel trucks. Featuring a 1-3/8 inch input shaft diameter and a 10-spline count, this upgrade is designed to enhance the performance and durability of your transmission. The comprehensive kit includes the essential input shaft, along with an input retainer, input seal, and input bearing to ensure a complete installation. It is important to note that this input shaft upgrade kit does not work with the stock clutch. For optimal performance and compatibility, an aftermarket clutch may be required. USA Standard Gear is recognized for its extensive inventory, experienced technical support, and industry-leading quality assurance testing, aiming to provide confidence and quick turnarounds for gearbox rebuilds.
