The GM version of the AAM 101⁄2 (foreground) in use since 2001 is just a new version of the tried and true Corporate 14-bolt (background). Parts from the GM to Dodge 101⁄2 do not interchange, though parts from the old 14-bolt do interchange with the new AAM 14-bolt. The center section is finned for added cooling and retains the removable pinion support and three-pinion bearings as compared to the Dodge’s two. Gearing and locker selections for the AAM 14-bolt axles are abundant.
