Out back is a GM 14-bolt axle that has a Detroit NoSpin locker, 4.56 gears, and a DIY4X diff cover. A DIY4X disc brake conversion kit allowed installation of GM disc brakes and a Parts Mike e-brake kit allows Davis to lock ’em down. The rear suspension consists of 63-inch-long 3/4-ton GM truck-application leaf springs with the factory overload leaf removed from each pack and a Pro Comp add-a-leaf installed in their place; custom leaf spring mounts that use the factory frame holes but move the mounting position forward 5 inches; FOA 16-inch-travel remote-reservoir shocks; and a Offroad Design 4-inch Shackle Flip Kit with 6-inch SuperShackles.
