The rear axle is a Dana 80 unit from a Cummins-equipped ’98 Dodge 2500 pickup. Like the front axle it has 3.73:1 ratio gearing and an ARB Air Locker. The rear suspension consists of 63-inch-long Deaver Spring long-travel leaf springs, 10-inch-travel Sway-A-Way RaceRunner remote-reservoir shocks, Prothane bumpstops, and a modified Speedway Engineering sway bar.
