These spindles feature a billet steel upright with a steel spindle snout and bolt-on billet aluminum steering arm, upper ball joint eye, and caliper bracket. The back side mounting surface of the upright is CNC machined flat so that the steering arm, upper ball joint eye and caliper bracket are mounted perfectly square with the spindle snout. These spindles are designed to eliminate flex. They are available to fit most standard asphalt chassis. Available with 5, 7 and 10 Deg. spindle inclination angles. The bolt-on caliper bracket is designed so it can be adjusted from 11 3/4" diameter rotors to larger diameter rotors simply by shimming the bracket.
