Axle Details
The GM 7.5" 10 Bolt axle, also known as the AAM 7.5", GM 7.6", and GM 7.625" axle is the most common housing used in GM G-body car vehicles and features a 7.5" diameter ring . The GM 7.625" version of the axle uses a slightly larger 7.625" diameter ring gear with 28 spline axle shafts, however, because both models use the same axle housing, the ring and pinion gears, differential carriers, and all other components are interchangeable between the two axles.

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