The AAM 11.5 still uses the 1 1/2-inch by 30-spline axleshafts similar to the Corporate 14-bolt, but the larger ring gear, massive housing, and disc brakes make it a great axle upgrade for a workhorse truck, or a diesel-powered trail machine on massive rubber. As the aftermarket grows and supplies diesel owners with higher-quality axleshafts, this Air Locker needs to be ready for any abuse sent its way, and one way ARB is preparing is by offering side gears for this locker for 35-, 37-, and 40-spline aftermarket axleshafts.
