Detailed Product Information
This Dorman 630-157 disconnect gear is engineered to replace the failed gear used in the front differential on a 2021 Ram 1500 Classic, w/Dana Axle. The original disconnect gear is not offered as a separate service part, so this OE FIX component gives technicians and owners a focused repair path instead of replacing the entire differential assembly. It also provides a cleaner alternative to used parts when servicing a Ram 1500 Classic front axle issue.
Key dimensions include a 16-spline configuration, 72.6 mm overall diameter, 33 mm overall width, 61.0 mm shift fork groove diameter, and 11.5 mm shift fork groove width. Dorman 630-157 cross-references 68257421AG for the same application.
What This Part Helps Fix
- Front differential disconnect gear failure
- Loss of 4WD engagement at the front axle
- Wear or damage to the original disconnect gear
- Need to replace a non-serviceable OE gear without buying a complete differential
- Repair needs on a 2021 Ram 1500 Classic, w/Dana Axle
Installation Notes and Tips
Verify axle type and match the listed dimensions before installation. This part is intended for the front differential disconnect assembly on the confirmed Ram application, so compare the spline count, groove diameter, groove width, and overall measurements to the original component before reassembly. Proper differential service procedures and final function checks are recommended after installation.
Quality Assurance
Dorman OE FIX parts are built to replace serviceable components that are not offered individually by the original equipment manufacturer. This approach supports a targeted repair for the front differential on Ram 1500 Classic applications while maintaining OE-style fitment requirements.
