Axle Details

The GM 7.2" axle can be found under a handful of GM's smaller SUVs and vans and features a clam-shell style carrier that houses a 7.2" diameter ring gear (7.250" in 2003 and older models) and uses 26 spline CV axle shafts.

Note: This axle has a Carrier Break and gear changes may require a different carrier or thick gears.
