BONOSS Forged Active Cooling Wheel Spacers
A guarantee of safety.
Explore High-Performance BONOSS Wheel Spacers
Active Cooling
BONOSS only uses high-grade forged 6061-T6billet aluminum alloy material for higher performance and safety
The tensile strength of 6061-T6 is over 310 Mpa, This means they provide stronger impact resistance, less fatigue strength, and longer service life range
Symmetrical petal shape grooves effective heat dissipation water debris protection
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
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.
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
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.
High Precision
BONOSS wheel spacers are accurate to 0.02mm which provides high quality and safety. In addition, a smooth installation experience.
Safer & Better
Both forged Aviation 6061-T6 and 7075-T6 feature good hardness and toughness, excellent wear resistance characteristics.
