Why CR BOOST

Built to outperform

Every CR BOOST spacer is forged, CNC-machined and anodized to aerospace tolerances — engineered to widen your track without compromising strength, balance or safety.

Forged Aircraft-Grade Aluminum

6061-T6 / 7075-T6 alloy forged under 1,200–1,600 tons of pressure for uncompromising structural rigidity and mechanical stability.

Hubcentric Precision · CB64.1

A 64.1mm machined bore centers the wheel on the hub — not the bolts — eliminating vibration for a perfectly balanced ride.

Active Cooling Design

Symmetrical pistol-shape grooves channel airflow across the disc for effective heat dissipation, plus water and debris protection.

Knurled Edge

Cross-hatch knurling increases air-contact area and relieves internal stress — and carries the laser-etched CR BOOST mark.

12.9 / 10.9 Forged Hardware

35CrMo alloy-steel bolts & studs in M14×1.5, heat-treated to Class 12.9/10.9 tensile strength for safe, precise torque.

Satin Black Anodized Finish

CNC CD-pattern surface, satin-blasted and anodized for corrosion resistance — finished with an anti-counterfeit authenticity mark.

About

Automotive parts
specialist

CR BOOST engineers precision wheel spacers and adapters for serious off-road and performance builds. We obsess over the details others overlook — forging pressure, hubcentric tolerances, thread-grade hardware and finish quality.

Every kit is built around one promise stamped on the box: Precision · Strength · Quality. No shortcuts, no counterfeits — just hardware you can torque down and trust.
