This anti-roll bar helps eliminate side-to-side body roll caused by engine torque trying to lift the right rear tire and the left front tire. Traction is more equalized. Kit includes parts and instructions for either crossmember tube mounts or separate frame rail mounts. Some bracket parts will need to be trimmed per application. Includes torsion tube, mount tube, poly bushings, plated steel arms, plated 5/8'' steel links, 7/16'' rod ends, housing tabs, bolts, lock nuts and mount hardware. Torsion tube is 1'' x 32''. Mount tube blank is 1-1/2'' x 29''. Links are 5/8'' x 9''. Fabricated steel arms are lighter than some brand X aluminum arms.
