The TERA60 HD Front Coilover W/Locking-Hub 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, HD Steering and Big Brake kit.
Engineered to integrate seamlessly with TeraFlex JK Coilover Kits, this axle is a true direct bolt-on solution. It features integrated Coilover Mount Brackets, bump-stop strike pads, high-clearance lower control arm brackets, and reinforced upper control arm mounts 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.
TERA60 HD Front axles also include HD Tie Rod and Drag Link, TeraFlex Big Brake kit, 35 spline axle shafts, sensors, TeraFlex HD wear adjustable Ball Joints and much more.
