TeraFlex is pleased to announce our new 70” wide Tera60 HD Front and Tera CRD60 HD Rear Axle Assemblies for the JL Wrangler/Unlimited. These heavy-duty axles are designed to withstand the abuse caused by heavier tire and wheel combos as well as rough terrain.

The Tera60 HD Front Axle Assembly features Locking Hubs, while the Tera CRD60 HD Rear Axle Assembly features Full-Float Axles. Both axle assemblies are available unloaded or complete with an ARB Air Locker and a choice of Super 60 ring & pinion gear ratios. Front and Rear Axle Assemblies are also available unloaded.

A must for anyone who takes their lifted Jeep off road!

UPDATE: Tera60 HD Front Axle Assemblies also fit JT Gladiator models.
