Heidts 4-Link Rear Suspension Kits RB-112

This Heidts 4-link rear suspension kit, part RB-112, is built around a Ford 9-inch rear end and bundles adjustable upper and lower trailing arms with trailing-arm mount braces, a single-adjustable coilover shock package, and an adjustable panhard bar, all in natural-finish steel with black polyurethane bushings.

What ships in this kit

Coilover springs arrive pre-installed in a gray/silver finish, and every trailing-arm hardware piece and mounting brace is included. A watts link, sway bar, rotors, and calipers are not part of this package, and neither is the differential housing, third member, or axle shafts, so budget for those on your own if you are starting from a bare rear end.

What to check before ordering

Heidts offers both bolt-on and weld-in installation for this kit, so review the instructions to see which fasteners your particular chassis calls for. Because this is sold for Ford 9-inch housings generally rather than one specific car, double-check your rear-end width and mounting points line up before ordering.

Does this kit include the rear differential? No, the housing, third member, axle shafts, brakes, rotors, and calipers are all sourced separately.

Can I adjust ride height after install? Yes, the single-adjustable coilovers and adjustable trailing arms both allow tuning.
