Speedway Motors is proud to introduce our exclusive 3-piece "Short Arm" Metric replacement spindle. 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. Accepts '79-Up GM Metric rotors, calipers, stock tapered lower ball joints and is reamed to accept 7 degree upper ball joints. These spindles IMCA/USMTS/USRA/UMP/Wissota approved for use in competition. 

Works as replacement for both right or left hand spindles. Steering arm and caliper bracket sold separately.
