UMI’s A-body bump steer kit (1964-1970) is designed to reduce or eliminate toe change during suspension travel (also known as “bump steer”). Reduction of bump steer improves handling and straight line stability and enhances overall precision of the steering system. These direct bolt-in kits allow the builder to relocate the outer tie rod end lower than stock (or higher if necessary). The stud taper is designed for exact factory fit for each application and is constructed of 4140 CrMo for strength and durability, no spindle drilling required. The adjuster is 6061-T6 Aluminum hex for lightweight strength and features a hard anodized protective finish. Kits include shims of 0.125”, 0.1875” and 0.250”. These race-tested bump steer kits are 100% designed and manufactured with pride in Philipsburg, PA – USA.
