Axle Details

The AMC Model 20 Axle, also known as the AMC 20, M20 and Jeep Model 20 axle can be found under older AMC cars, a handful of CJ model Jeeps, and in IFS and IRS configurations in the military and civilian Hummer H1. It features an 8.875" diameter ring gear with 29 spline axle shafts that are attached via bolts instead of c-clips.

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