Good To Know

Q: Is this sprocket a direct replacement for my differential? A: It is listed for the platforms shown in the title, but differential internals can vary by build. Confirm your rear axle part number or VIN before ordering.

Q: Can I replace just the sprocket without touching the rest of the differential? A: Differential work usually requires opening the housing and checking gear mesh, bearings, and preload. Replacing the sprocket alone is possible when the other internals are still in good condition.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
