Black Diamond X2 Jeep Suspension Kit - Leaves To Coilovers

The X2's marquee upgrade is Superlift's Torque Fork traction bar. Similar in design to the XCL's three-link front arms, the Torque Fork uses two shackles to control spring wrap throughout suspension cycling.

Other options are extended Rockrunner link-arm ends for up to 3 inches of wheelbase stretch as well as the eXtreme Clearance flat skidpan, which requires floorboard modifications. Front-axle weld-on link-arm brackets are available that essentially emulate the OE TJ arrangement are available for popular frontend swaps, as are spring pads for common rear axle swaps.

The X2 installation also provided an opportunity to try Pro Comp's new Xtreme MTs. Since the X2 fits up to 37-inch-tall tires, we chose the 37x12.50-17, one of a handful of fitments available at press time. A trade-off is a D load range-stiff for a short-wheelbase Jeep.

One compromise with production alloy 17s is limited widths and backspacings. Since this YJ is a daily-driver, we stuck to aluminum wheels to minimize rolling mass. Pro Comp series 1023 got the nod because the 17x9 size has 4.5 inches of backspacing.

Longer bolts are included for securing the bracket to the axlehousing through the diff cover.
