ABSTRACT:
The quick-change adjustable track center front hub assembly is secured to a spindle axle of a sprint car by a friction drive bearing system located between the spindle axle and the front hub assembly. The bearings are spaced apart to provide increased side and torsional load carrying capability. In addition, the hub includes a section of external splines for accepting at least one spacer and a wheel center section both having internal splines for mating with the external splines on the hub. A single lug nut connects to the outboard end of the hub for securing the spacers and wheel center sections to the front hub assembly to provide a quick-change arrangement not found before in sprint-type cars. A brake rotor is attached to the hub inboard of the spacers and wheel center section, thus allowing unimpaired accessibility to the wheel center section and spacers for quick-changing and adjusting the track center of the front wheels of the sprint-type cars.
