The hefty Corporate 14-bolt rear axle has been re-geared using Yukon 5.13:1 gears. It also sports a durable Detroit Locker and a TSM disc-brake kit with calipers pirated from a Cadillac. The differential is protected from trail damage by an Avalanche Engineering Rock Ring. The rear suspension consists of 4-inch-lift BDS leaf springs, a 4-inch shackle flip, ORD greasable polyurethane spring bushings, and single Rancho 9012 shocks mounted to a custom Palm-fabricated inboard shock relocation crossmember. In an effort to help keep the tires from contacting the body, and to improve departure angle, Palm fabbed a new rear leaf that he added to the leaf pack that moves the axle rearward 1.5 inches. The axle receives power from a High Angle Driveline CV-equipped driveshaft. Finally, because the axle is slightly narrower than the front axle, Palm installed a pair of Weird Harold's Cool Parts 2-inch hard-anodized wheel spacers to correct the front-to-rear wheel track.
