TeraFlex 4171538 TeraCRD60 HD 68" Semi-Float Rear Axle Assembly 5.38 R&P ARB Locker 0-6" Lift

The TeraFlex TeraCRD60 HD Rear Axle Assembly is a purpose-built, heavy-duty rear axle solution designed for the Jeep JT Gladiator. Whether you're replacing a bent, broken, or damaged axle — or simply upgrading the stock unit's weak points — this assembly delivers the strength and durability needed for serious off-road use, including Rubicon models. This configuration includes a 5.38 ring & pinion ratio and an ARB Air Locker for maximum traction in extreme conditions.

At the core of this assembly is TeraFlex's exclusive Constant Radius Design (CRD), which maintains high ground clearance regardless of pinion angle adjustments — a critical advantage when running a lift. The housing is fully compatible with all Super 60 gear ratios, making it ideal for extreme-duty applications that demand superior ring & pinion strength.

This axle ships complete with Spicer Super 60 bearings, semi-float rear axle shafts with 40 splines, and all necessary sensors. The heavy-duty housing features smooth-profile axle tubes, all required mount brackets, control arm bushings, and a direct bolt-on fit for the JT Gladiator platform.
