Upgrade your stance and wheel fitment with American-made precision. BSB USA wheel spacers are engineered and machined in the United States from high-strength 6061-T6 billet aluminum. Each spacer is CNC-machined to exact tolerances with a precision-machined 124.1mm center bore for an accurate hubcentric fit, then anodized black for corrosion protection and a clean finish.
Built for 2011 and newer Chevy Silverado and GMC Sierra heavy-duty trucks with an 8x180 bolt pattern. These 3/8" (9.5mm) slip-on spacers move each wheel outward 3/8 inch, adding clearance for brake calipers and suspension components and filling out the stance for wider wheels and tires.

Installation:
Clean the hub face, slide the spacer over the factory studs until it sits flush on the hub, then mount the wheel with your original lug nuts. Confirm full thread engagement on every lug nut (7.5 turns on 14x1.5); if your studs are too short, install extended wheel studs before use. Torque with a hand torque wrench to the factory spec, not to exceed 110 ft-lbs, and re-check torque after the first 25 miles.
