Speedway Motors is proud to introduce our exclusive 3-piece Pinto replacement spindle and rotor front end kit for even more value added savings! Our advanced engineering techniques allowed for a redesign of the spindle in a newly forged, heat-treated steel design that is stronger than the original. These spindles serve as a replacement for cars currently running Pinto/Mustang II setups. The 8 degree pin inclination not only improves handling and driver feel, but also dynamically adds cross weight to the car during counter steering which leads to increased drive off the corner. The shortened, dropped steering arm reduces spacing requirements on outer tie rods and minimizes bump steer while improving overall strength.

Spindle is reamed to accept 7 degree upper ball joints. The unique three-piece construction provides for fast, convenient and affordable replacement of individual components in the event of a crash. These spindles are 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.
