Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- GM 7.5-inch / 7.625-inch 10-bolt axles with verified 26-spline carrier and appropriate 3.73 gearing
Product Overview
A gear change can alter acceleration and cruising rpm, while a limited-slip unit helps distribute drive between both rear wheels. Proper installation requires measuring gear backlash and pinion depth, not simply bolting in new gears.
Broken gears, worn carrier bearings or a planned performance rebuild are reasons to service the differential.
Key Features & Performance
- 3.73 axle ratio
- 26-spline application
