Description

The Zumbrota Drivetrain ZMSR24025 is an aftermarket synchro ring specifically designed for the 3rd and 4th gears of NV4500 manual transmissions. This component is crucial for smooth and efficient gear changes, ensuring reliable operation of your vehicle's drivetrain. These specifications contribute to its ability to handle a rated Gross Vehicle Weight (GVW) of up to 14,500 lbs., making it suitable for heavy-duty applications. The transmission requires approximately 1 gallon of lubricant, and it is critical to use the correct synthetic lubricant to prevent failure and maintain warranty coverage. This synchro ring is compatible with both current production Dodge NV4500 and GM NV4500 transmissions. Early GM units from 1993-1994 with a 6.34 to 1.0 first gear ratio may have different specifications compared to later models. Beginning in 1995, all GM units shared the same gear ratios as the Dodge units.
