Nestled underneath the rear of the CJ is a GM 14-bolt axle. It has been fitted with 5.13:1 cogs, a Detroit Locker, Ballistic diff cover, and 3/4-ton pickup truck-application disc brakes. The flexy rear suspension is almost a carbon copy of the front in design and features. All of the custom shock hoops under the CJ are made from 1-inch-diameter, 0.250-inch-wall DOM tubing. Hilton stretched the CJ's wheelbase to 101 inches, which is 20 inches more than stock.
