They are precisely cut with some “hollow holes”. Due to these hollow holes, the average weight of each spacer is more than 30% lighter than the previous-gen product.

BONOSS manufactures wheel spacers with high-grade forged billet aluminum alloy which features many desirable properties such as wear-resistance, impact resistance, high-temperature resistance.

Based on traditional hub centric wheel spacers, BONOSS has optimized this design, making them fit more perfectly, safely, stably, and further reducing the chance of high-speed vibration.

For decorative reasons, knurling can enhance the aesthetics of spacers. It can also enlarge the side area so that it can contact more air, boost the heat dissipation effect, and also reduce internal stress.

It is designed to easily dismount the spacers, improving user experience. Normally, using a screwdriver can easily remove the spacers, simple and efficient.
