The GM 8-1/2" 10 bolt rear axle first appeared in vans 1976, however it did not come into widespread use in GM trucks until 1979-1981 when it replaced the 8-7/8" truck axle. From 1982-1987, this 10 bolt axle was used by all the GM 1/2 ton truck models. From 1988 on, the 8-1/2" axle has continued to be used for 1/2 ton class vehicles, plus some 3/4 ton vans. When AAM acquired the GM axle manufacturing assets, the 8-1/2" was renamed the AAM 860 8.6" 10 bolt rear axle.
