OverviewMill DirectThe heart of our wheel spacer is in the material, and we take this very seriously. All of our aluminum is made in the USA and sourced from the mill directly. We even briquette all of our chips and recycle them back to the same mill. It's a happy cycle and keeps the quality in the purest form.Concentricity MattersOur made in USA lug nuts are cold headed, an old-school manufacturing process that gets its roots from Detroit. Precision matters; our lug nuts hold runout less than 2% of the thread diameter. This high accuracy helps keep your spacers where they belong, safely on your axle.Chromoly Wheel StudsWith our strong racing background, we know how important wheel studs are. Every wheel spacer is outfitted with 4140 chromoly wheel studs that not only exceed the strength of OE but are coated with GEOMET for 10X the corrosion resistance over zinc. Your wheels will thank you.Made in USASince starting this hobby in 1999, we take great pride in manufacturing in-house. Know that when we say MADE IN USA, we mean it. Every component of every Wheel Spacer Kit, from spacers to lug nuts, from printed box to instructions, are made right here in the USA.
