Overview
The G2 Axle and Gear AAM Master Conversion Rear Install Kit is a master installation kit for the rear axle of the 2014–2016 Dodge Ram 2500 3/4 ton, used to run an early style 11.5-inch ring and pinion in the new 11.8-inch housing.
G2 describes its master installation kits as everything needed to set up a ring and pinion, including Timken bearings, ring gear bolts, shims for pinion and carrier preload, a pinion seal and a pinion nut. This version is for the rear only and adapts the earlier 11.5-inch gear to the 11.8-inch housing.
AAM here stands for American Axle Manufacturing, the maker of the housing. The conversion lets an earlier 11.5-inch ring and pinion work in the newer 11.8-inch housing, which is useful for owners who want to keep an existing gear style. The Timken bearings and shims in the kit are the parts that set the preload. G2 describes the kit as a master kit, meaning it is intended for jobs where the bearings are replaced as well.
