Racing Wheel Hubs, Bearings, Seals & Components

Wheel hub assemblies are some of the most crucial components of your racing vehicle. They are the components that hold your wheels attached to the axles while allowing them to rotate freely. Also, these components work in conjunction with your steering system. Such an assembly consists of a hub and a bearing pressed inside of it. A hub carries lug studs used for attaching the wheel with lug nuts. The inner race of the bearing is splined to the axle, while the hub itself is bolted to the steering knuckles (on the front axle). Brake rotors with calipers are located between the hubs and the rims.

Also, in the majority of modern vehicles, such an assembly houses an anti-lock braking system (ABS) sensor. It sends signals to the electronic module that evaluates information about the rotational speed of each wheel during braking and engages the ABS if one or more tires slip. In older off-road 4WD vehicles, locking hubs can be used to either lock the wheels on the front or rear axle or release them free when there is no other way of disengaging a 4×4 mode. Sometimes hub assemblies are simply called wheel bearings. Their efficient and trouble-free operation ensures a smooth, comfortable ride, while also providing greater fuel economy.

In a racing environment, when every split second counts, the condition of your hubs may determine the difference between the win and failure. If you feel steering wheel vibration, hear rumbling, humming, or squealing noise from one of your wheels, it is time to replace your wheel bearing. Also, an ABS signal light on your instrument panel may come on if the sensor in your hub is malfunctioning. A bad bearing inside your hub prevents the wheel from turning smoothly. It causes accelerated wear which may lead to a dangerous failure. Visit our store to choose from a wide variety of premium racing wheel hubs, bearings, seals, and related components.
