All of our wheel spacers and adapters are proudly made in the USA, custom-crafted from high-quality billet aluminum 6061 T6 and steel 1018 grade. We start by cutting pieces from billet bars using a CNC band saw, followed by precise lathe and milling processes. Our products are made to order, available in sizes ranging from 6mm to 6 inches, and can accommodate wheel combinations from 3 lug to 10 lug.
