The hub-centric design of the wheel spacers makes them fit tightly with the axle hub and the wheel of your vehicle, avoiding the damage caused by the vibration among three parts. If you’re confused with which type of wheel spacers is more suitable and safe for your vehicle, just remember to select hub-centric ones. What are the features of hub-centric wheel spacers? How can it help your drive? And How to choose the right one? The answer is below.

What are Hub-centric Wheel Spacers?

Hub-centric wheel spacers (also called wheel adapters) refer to wheel spacers designed to center with the hub. The center ring of the wheel spacer has the same diameter as the axle assembly and as the contact surface on the wheel originally fixed to the axle with studs or bolts. That means the wheel spacer becomes a natural component between the axle and the wheel as long as their quality can be promised. Just as a cheese placed in the sandwich, you will be surprised with the stunning performance it takes.

How can Hub-centric Wheel Spacers Help Your Drive?

Minimize the Vibration – Hub-centric minimizes the clearance between the axle and the center hole step of spacers, and which between the stock studs/bolts and the holes on the wheel spacers used to through the studs or bolts. Some spacers users complain about the vibration after installing adapters and blame the adapters themselves. This is likely due to you falsely bought the lug-centric wheel spacers which can not perfectly fit with the hub, or you didn’t measure the diameter of the hub and the thread of studs/bolts. Yes, the wrong data of stud or bolts also impacts the tightness. Generally, carmakers will public their info of bolt patterns in the manual handbook, and professional wheel spacers companies also have their database. But if you modify with aftermarket accessories, the data needs to be calculated according to many configurations.

Transfer the Stress – Besides the advantage of vibration-avoid, hub-centric design plays a vital role to transfer the stress from the wheel spacers to the hub, which is in accordance with the principal car designers make to wear the vehicle load. Compared with the two points above, lug-centric spacers expose their shortage. To some extent, adding a wheel spacer equals a new hub.

How to Choose the Right Hub-centric Wheel Spacers?

To get the perfectly performed hub-centric wheel spacers, you should select carefully the quality and the size. About size, if you can not figure out the definite specs of your car, tell us your model, year, and mods. BONOSS has long-term data accumulation gained from lots of real installation cases. And we always catch up with the news about upcoming models such as the 2022 Lexus LX 600, 2022 BMW X8, 2022 Toyota Tundra, and 2022 Audi Q9. Any model is available. The quality of wheel spacers has been a heated topic for many years. Many people would worry about the break of spacers and studs/bolts.

-Actually, BONOSS wheel spacers have passed the SGC and TUV tests 66 times. The materials used to produce the spacers are aerospace aluminum 6061-T6 and 7075-T6. (Specific data is placed at the end of the text.)

-The matching studs, nuts, and bolts are all proved by international authoritative performance tests SGS and TUV.

“Active Cooling” technology has been patented worldwide, improving heat dissipation efficiency.

Forging process along with CNC machining gives wheel spacers one-time forming shapes and 0.02mm tolerance precision.
