The Tera CRD60 HD Rear Coilover Full-Float Axle Assembly is designed as a direct bolt-on for the TeraFlex Coilover System and is available with pre-installed Super 60 gears, an ARB air locker and full-float axle shafts.
Engineered to integrate seamlessly with TeraFlex JK Coilover Kits, this axle is a true direct bolt-on solution. It features integrated Coilover Mount Brackets and bump-stop strike pads, to handle the increased loads and articulation of a TeraFlex/Falcon Coilover Suspension System.
Available with Super 60 ring & pinion gear ratios of 4.30, 4.88, or 5.38, this 70" wide axle bolts directly into all JK models equipped with a TeraFlex Coilover System—eliminating the fabrication and guesswork typically associated with axle upgrades.
