Hotchkis double-adjustable upper trailing arms for 1964–1967 GM A-Body vehicles. These heavy-duty, double-adjustable arms allow in-car pinion angle adjustments to reduce vibration and improve traction, and use Swivel-Max bushings for non-binding articulation. Constructed with TIG-welded steel and billet aluminum sections, they arrive ready to bolt in and include polyurethane rear end housing bushings for durability.
