BSB USA Products
CNC-machined from U.S. billet aluminum. Engineered for strength. No BS.
The Parts We Build
Every BSB spacer starts with U.S.-sourced billet aluminum, CNC-machined to exact specs for strength, precision, and reliability. From bolt-on spacers to custom adapters, every part is designed, cut, and finished right here in the USA — with no gimmicks, no shortcuts, and no BS.
Built for Every Kind of Driver.
Trucks & Off-Road
More clearance. Bigger tires. No compromise.
Whether it’s a lifted F-150, Jeep Wrangler, Tacoma, or Bronco, our bolt-on spacers and adapters are built to handle heavy loads, off-road abuse, and aggressive stance setups.
Street & Performance
Dialed stance. Street-ready precision.
From muscle cars to daily drivers, our slip-on and bolt-on spacers dial in the stance and handling of everything from Camaros and Challengers to BMWs and Civics. Engineered for hub-centric fitment and perfect balance.
Racing & Motorsports
Proven strength at speed.
Racing demands precision, and so do we. BSB spacers and adapters are trusted by drivers in autocross, drifting, and track-day builds for their accuracy and reliability under pressure. Machined to exact specs, proven on and off the track.
Powersports
Precision built for the wild.
Built for side-by-sides and UTVs that see real abuse — sand, mud, trails, and rock. Our spacers are machined from the same billet aluminum as our automotive products, giving powersports drivers the same level of reliability and precision.
Built Strong. Built Different.
We’ve been in the spacer business for 15+ years. We know what works, what doesn’t, and what shops care about. Every BSB part is machined from billet aluminum, inspected before it leaves, and designed for maximum safety and reliability.

Frequently Asked Questions
Are BSB USA spacers made in the USA?
Yes. Every BSB USA wheel spacer and adapter is designed, CNC-machined, anodized, laser-engraved, and assembled in the United States.
We use U.S.-sourced billet aluminum and manufacture everything in-house to ensure consistent quality, precision fitment, and true American craftsmanship.
What materials are used in BSB USA wheel spacers?
BSB USA spacers are machined from U.S.-sourced 6061-T6 billet aluminum — the same high-strength alloy used in aerospace and motorsports applications.
This material offers the ideal balance of strength, weight, and corrosion resistance, ensuring durability under street, off-road, and racing conditions.
What’s the difference between bolt-on and slip-on spacers?
Bolt-on spacers have built-in studs and bolt directly to your vehicle’s hub, then your wheels attach to the spacer — ideal for larger fitment changes or thicker spacer sizes.
Slip-on spacers simply slide over your existing studs and sit between the hub and wheel — perfect for minor offset adjustments or fine-tuning stance and clearance.
