AAM Pinion Shaft

7 of 10
The AAM 11.5 is similar to the Corporate 14-bolt in that it uses side preload adjusters. However, unlike the 14 bolt, the AAM only uses two pinion bearings instead of three and a removable pinion support. Nonetheless the giant AAM pinion shaft (see photo number 1), the massive ring gear, and now the added selectable traction of the ARB should help these new Dodges start seeing more dirt in addition to their already proven towing ability.
