Out back, the simple suspension uses custom 64-inch leaf springs (the stock springs were 52 inches in length), a 6-inch Offroad Design shackle flip, and Skyjacker shocks. The suspension tethers a GM 14-bolt axle (replacing the factory Eaton axle) that has a Detroit Locker, 4.56 gears, and a Fab Fours diff cover. Both the front and rear axles are fed by custom driveshafts with 1410 U-joints.
