TeraFlex 4006430 TeraCRD60 HD 70-Inch Full-Float Rear Axle Assembly with ARB Locker and 4.30 Ring & Pinion

The TeraFlex TeraCRD60 HD Rear Axle Assembly (Part #4006430) is a complete, fully loaded rear axle solution engineered for the Jeep Gladiator JT. Built around TeraFlex's exclusive Constant Radius Design (CRD), this heavy-duty Dana 60-based axle delivers exceptional ground clearance that remains consistent and unaffected by pinion angle adjustments — a critical advantage when running a 0–6 inch lift.

This assembly arrives pre-configured with a Spicer Super 60 4.30 ring and pinion, an ARB Air Locker, and a full-float outer axle setup, making it an ideal replacement for bent, broken, or damaged factory axles, or as a direct bolt-on strength upgrade targeting the known weak points in the stock drivetrain.

The CRD60 housing features smooth-profile surfaces, heavy-duty 3.25-inch O.D. axle tubes with 0.375-inch walls, all necessary mount brackets, and control arm bushings. The 1350 series pinion yoke and 35-spline shaft design are built to handle extreme-duty off-road use with maximum durability.
