Wider track for a better corner! BONOSS hub centric wheel spacers bring your rims and tires outwards so that they can flush with the fender flares, giving your vehicle an aggressive and powerful stance. A wider wheel track means better traction, hence increasing handling. With car spacers, you can install bigger wheels and barke calipers without rubbing against the frame, axle, or other suspension components.

Forged 6061-T6 or 7075-T6 Aluminum

BONOSS only uses high-grade forged 6061-T6 or 7075-T6 billet aluminum alloy material for higher performance and safety. The tensile strength of 6061-T6 is over 310 Mpa, while the tensile strength of 7075-T6 is over 572 Mpa. This means they provide stronger impact resistance, less fatigue strength, and longer service life range.

ISO Grade 12.9 Wheel Studs

The matching wheel studs of BONOSS tires spacers applied high-strength JIS SCM440 steel material. They have achieved ISO standard grade 12.9, tensile strength ≥ 1,220Mpa, limited life range test ≥ 2,000,000 stress cycles without damage, ultimate tensile load ≥ 152,000N, hardness (HV) ≥ 395,
NSS ≥ 500H…

ISO Grade 10 Lug Nuts

The matching lug nuts have achieved ISO standard grade 10, proof load ≥ 1110Mpa, hardness (HV) ≥ 349… Each BONOSS lug nut is “BONOSS engraved”, meaning these lug nuts are made by BONOSS’s factory, the quality is guaranteed, customers’ interests are protected, and BONOSS takes the quality responsibility.

Full-cone Seat

Full-cone seat design provides larger contact area, more force acreage and better fitting. Using the full-cone seat style of fastener for the wheel spacer installation work can not only bring better installing experience but also more particularly guarantee.

Multi-stage Hubcentric Design

Based on traditional hubcentric wheel spacers, BONOSS has optimized this design to further reducing the chance of high-speed vibration, it is called multi-stage hubcentric design. According to the actual test, the effect of BONOSS multi-stage hubcentric wheel spacers is far better than the common alternatives, which fit more perfectly, safer, and more stable.

Side Knurling Design

For decorative reasons, knurling can enhance the aesthetics of spacers by introducing an attractive pattern to the side surface. It can also enlarge the side area so that it can contact more air, boost the heat dissipation effect, and also reduce internal stress. That means improving the performance, strength, and durability of the spacers for rims.

Disassembly Grooves

Disassembly grooves means the small notches which are distributed on the corner of BONOSS truck spacers. It is designed to easily dismount the spacers, improving user experience. Normally, it leaves a limited clearance between the axle plate and spacer, using a screwdriver can easily remove the spacers, simple and efficient.
