Are Wheel Spacers A Good Idea for Mercedes-Benz S400 W223-xu (1)

Toyota Alphard uses the Bolt-on structure and is suitable for retrofitting with BONOSS Active Cooling wheel spacers, which are designed based on the Japanese car brand structure. Generally speaking, wheel spacers are divided into slip-on wheel spacers and bolt-on wheel spacers, the hub assembly of Japanese cars generally has 5 studs protruding, and the nut and studs threads bite together to lock the wheel, the slip-on wheel spacers are only applicable to European models (German models for example) The bolt-on wheel spacers provide wheel bolts (studs) for nut locking, meaning that the wheel spacers are threaded through the studs and installed on the hub assembly by the lug nuts that come with the wheel spacers, and the OEM lug nuts are locked after the wheel is installed.

Why Hub Centric Is Important?

Wheel spacers have not only the difference between slip-on and bolt-on but also the difference between hub-centric and lug-centric. BONOSS believes that using hub-centric wheel spacers is safe, the design of wheel spacers hub centric is based on the contact surface of hub centric on the inside of the wheel and hub assembly, the purpose is to make the wheel spacers fixed by the center ring of the hub assembly.

We found that there are some lug-centric wheel spacers and hub-centric wheel spacers with insufficient precision in the market when using there is a shaking situation, and it is more serious when the vehicle is running at high speed. The reason for this phenomenon is that the lug-centric wheel spacers are only fixed with lug nuts, and the hub centric on the inside of the wheel is not in contact. With the feedback from the nuts, the hub becomes the uneven force of the bolt hole, and the change of bolt hole diameter leads to the loosening of the parts and the shaking of the vehicle.

Hub centric is recognized by more and more people, the above-mentioned lack of precision hub centric may lead to jitter is also BONOSS analysis of poor quality products on the market, wheel spacers hub centric accuracy is often controlled within the range of 0.1mm, and there are some production wheel spacers manufacturers do not get a first-hand measurement data, only through the aggregation of data from other sites, which naturally leads to the lack of precision of hub centric, which affects the wheel spacers and hub assembly fixed there may be a difference of 0.1mm, this difference is magnified at high speed, to produce shaking situation, and BONOSS through the first-hand measurement to obtain the most accurate data through first-hand measurement, and controls the accuracy to a more precise 0.02mm under factory CNC machining, this measure pushes the professionalism of wheel spacers to a higher level.

Are Aluminum Wheel Spacers Best Choice?

At present, yes. Wheel spacers are produced from aluminum alloys that have been proven to be the most suitable materials over a long period of time, depending on the category: 6061, 6061-T6, 6082, 6082-T6, 7075, and 7075-T6. As of now, BONOSS chooses 6061-T6 and 7075-T6 as the main materials, depending on the tensile strength and yield strength of these two materials. Unlike the materials chosen for body modifications, such as carbon brazing or steel, which have their advantages, the requirements for this particular part are a certain strength to support the pressure, a certain tensile strength to guarantee the toughness of the material and, more importantly, a weight limit, as the weight under the spring will directly affect the speed and fuel consumption of the vehicle. BONOSS has been tested by SGS, ISO, and TUV to ensure the safe use of 6061-T6 aluminum alloy material in the vehicle, while the better performance of 7075-T6 material is a better choice.
