NV4500 Mainshaft Reverse Gear for 97+ -Aftermarket




NV4500 Mainshaft Reverse Gear for 97+(Aftermarket)

Current production Dodge NV4500 and GM NV4500 share the same gear ratios. Early GM units (93-94) were built with a lower first gear ratio of 6.34 to 1.0. These low-geared GM boxes have since been discontinued and are generally much more difficult to obtain. We are able to provide new and remanufactured NV4500s with these early gearsets.

 Beginning in 95’, all GM units were built with the same gear ratios as the Dodge unit.

You MUST use the correct synthetic lubricant. The GM part no. for the correct oil is 12346190 (quart). The Dodge part number for the same oil is 4874459   Use of ANY other oil in the NV4500 will lead to failure and also voids any chance of a warranty claim.
