Axle Details
The GM 9.5" axle can be found in the rear of most GM mid-size trucks and SUVs. It features a large 9.5" diameter ring gear and accepts 33 spline semi-floating axle shafts that are held in place by c-clips. In 2014 the GM 9.5" axle was upgraded and a 12 bolt differential cover was used to distinguish it from the older axle. Gears, lockers, and installation kits are not compatible between the older 14-bolt and newer 12-bolt GM 9.5" axles.
