Proudly made in the USA, our 10x285 hub centric wheel spacers and adapters are designed for dually trucks running 10-lug semi wheels. Ideal for setups with 13.5” or wider tires where the rear duals may rub—these spacers help create proper clearance. We also offer adapters to convert from 10x285.75 to the military 10x335mm bolt pattern. Built for heavy-duty performance using 6061 billet aluminum or 1018 steel.
