The body includes a central hub, an outer rim, and a plurality of structural arms connecting the outer rim to the central hub. The central hub includes a pair of concentric hub walls with a plurality of spoke ribs disposed between the hub walls. The outer rim includes an annular groove in its upper surface as well as a plurality of support ribs. Each of the structural arms has a T-shaped cross section. The spacer has five bolt holes that are configured to work with a single center mount, two point, three point, or a four point mounting pattern. The spacer is fabricated from a non-metallic material such as a high strength, lightweight plastic or fiber reinforced plastic.
