An ORU disc-brake conversion kit allows fitment of disc brakes with 12.5-inch-diameter rotors to the beefy 14-bolt rear axle. The braking system is fed fluid by an ORU Hydroboost unit and master cylinder, and the fluid is carried by custom Orme Brothers brake lines. The 14-bolt axle also features a Detroit Locker and 5.13:1 gears. The rear suspension is simple and effective, and includes Atlas leaf springs and Bilstein shocks. There's plenty of space in the fenderwells for the 40-inch Pro Comp Xterrains to travel freely, and even enough room for the 44-inch Boggers that Rozo uses when traversing really deep mud.
