There can be no doubt that the hub-centric wheel spacers are better and safer for reducing vibration.

There are two distinct types of wheel spacers found on today’s market: hub-centric wheel spacers and lug-centric wheel spacers.

Why Do You Need Wheel Spacers with Hub Centric Rings?

[fusion_dropcap color=”#EDC657″ text_color=”” boxed=”no” boxed_radius=”” class=”” id=””]W[/fusion_dropcap]heel spacers are an economical way to get a wider track and more stability which have proven their effectiveness in racing cars for decades. There are two distinct types of wheel spacers found on today’s market: hub centric wheel spacers and lug centric wheel spacers. Hub centric wheel spacers are centered by the center bore of the wheel and the hub flange. They usually come with a hub centric ring which is made to the size of the axis of a particular car. The connection is called hub centric because of wheel links with the axle hub and centers. Lug centric would mean they are centered only by the torque of lug bolts/nuts, rather than the hub flange. They commonly come with no hub centric rings. This makes them compatible with more vehicle models. But whether these new spacers are hub centric or lug centric will determine just how they fit on the vehicle, as well as where the vehicle weight sits.

Basically, hub centric wheel spacers mean their center bores are designed to fit perfectly on the axle hubs and the wheels. In this way, the wheels are centered by the hub connection and the lugs can hold it flush against the mounting plate. This allows the wheel to support the vehicle’s weight and fill the remaining space for a more tightly fit, reducing vibration.

However, lug centric wheel spacers mean their center bores are made to fit many different vehicles. In a lug centric design, the wheel is attached and centered by the lug nuts or wheel bolts– instead of the hub. Lugs can be bent under force and provoke vibration in the car.


Another reason to use hub centric spacers is the conversion ability to install aftermarket rims with bigger hub diameter on the vehicle properly. Most originally equipped wheels are hub centric in design. The center hole of these wheels is the actual center bore that perfectly fits the hub flange. Hence, these wheels can be properly mounted and accurately balanced. But many aftermarket rims are made with larger hub diameters. This helps to increase the number of models the wheel fits.

Some aftermarket wheel manufacturers claim that all of their wheels are hub-centric. As a matter of fact, they equip the wheels with proper hub centric spacers instead of custom-make the wheels of your vehicle hub diameters. Truly, hub-centric spacers are around as important for aftermarket wheels as wheel bolts/nuts are. And for safety and quality, purchasing from a professional manufacturer is trustable and cost-effective. For correcting wrong ET/offset, hub centric wheel spacers are necessary equipment. Don’t be underestimated that buying some low-quality spacers at a low price. It is for your driving experience, furthermore, for your life safety.

Bolt-on Wheel Spacers

Bolt-on spacers are bolted to the existing studs with the provided lug nuts and then using your stock lug nuts to secure the wheel on the new studs pressed into the spacer.

Slip-on Wheel Spacers

Slip-on wheel spacers slide over your existing wheel studs. They are installed between the hub assembly and the wheel. If you need less than 15mm, we recommend these.


Custom Wheel Adapters

Wheel adapters can change the bolt pattern and center bore to allow you to mount various wheels. If you intend to convert PCD, then wheel adapters will be an effective solution.
