The Hub-Centric design centers the wheel over the hub providing the best fit possible and the proper clearance for brake rotors, steering components and suspension. Better fit, no wheel vibration! Stainless steel button-head socket cap screws around the perimeter of the outer wheel face give a great 3-piece look, and also let you accessorize with our optional trim ring. Each wheel includes a UV-treated polished center cap that replicates a manual hub for that off road look.
