The GM 9-1/2" semi-float rear axle was introduced in 1981 for 3/4 ton trucks as a lower cost replacement for the full floating 10-1/2" 14 Bolt axle used on 1973-1980 3/4 ton models. Starting in 1988, the 9-1/2" axle is also used on 1/2 ton heavy-duty models. The GM and AAM 9-1/2" axles are the same. The name difference is due to GM selling it's axle group to a group of investors who named the new company American Axle Manufacturing. The 9-12" axle design has remained pretty much unchanged over the years with the exception of seal changes and brakes.
