Speedway Motors is proud to introduce our exclusive 3-piece 1979-Up GM Metric midsize spindle and rotor front end kit for even more value added savings! Our advanced engineering techniques allowed for the recreation of an OEM spec spindle in a newly forged, heat-treated steel design that is stronger than the original. The unique three-piece spindle construction provides for fast, convenient and affordable replacement of individual components in the event of a crash. These spindles IMCA/USMTS/USRA approved for use in competition.

Kit includes 2 spindles, 2 bolt-on steering arms, 2 metric caliper brackets, 2 AFCO rotors, 2 bearing/seal/lock nut kits, and necessary hardware. Assembly is required. ‘Metric’ GM calipers and slider bolts are sold separately and available as suggested below.
