Product Overview
A limited-slip differential upgrade can improve how torque is delivered to the rear wheels. Rebuilding the axle also requires careful ring-and-pinion setup, bearing preload and backlash adjustment; an incorrect carrier or spline count will not work.
Key Features & Performance
- Limited-slip carrier, 3.73 gear set and bearing/install kit as specified by supplied package
Replaces / Cross-References
- GM7.5-373
Common Reasons for Replacement
Traction upgrade, damaged carrier, worn differential bearings or axle-gear ratio change.
Fitment Notes
Measure ring gear diameter; verify carrier series, axle splines, ABS/tone ring, housing year and pinion details.
