For the ultimate in dragster performance! Each of Pitsco’s Premium Outside Front Wheels is precision machined from black acetal – not injection molded like standard wheels. Acetal’s excellent dimensional stability, toughness, and abrasion resistance result in wheels with perfect balance, consistent weight, and true roundness. Each set of two wheels comes with a hard, smooth, low-friction chrome/moly axle. These wheel sets are not for just any CO2 car!
