NV4500 3rd & 4th Gear Synchro Ring-Aftermarket

NV4500 3rd & 4th Gear Synchro Ring (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.
