This improves handling, straight line stability, and overall precision of the steering system. The kit includes a heavy-duty 5\/8 bolt for the outer tie rod stud to increase strength over the factory tapered design. The adjuster is made of 6061-T6 Aluminum hex for lightweight strength and features a hard anodized protective finish. Shims of 0.125\", 0.1875\" and 0.250\" are included in the kit. These bump steer kits have been race-tested and are proudly designed and manufactured in Philipsburg, PA, USA. Note: Spindle drilling is required to accept the 5\/8 adjustment bolt. Once drilled, the spindle cannot be returned to the factory taper. For the 1971-1972 GM A Body, the kit uses the factory inner tie rod. If replacement is required, use Proforged 104-10016 or an equivalent, (2) are required.
