Steering Wheel Hubs

Steering Wheel Hubs

The steering wheel hub keeps your steering wheel securely attached and provides important wiring connections for vehicle systems including the airbag. This is also a crucial component in race cars that must maintain a quick release for adjusting the steering wheel while racing.

Most quick steering hubs have a universal center spline and can be used with any aftermarket steering wheel with the right adapter. Choosing the correct bolt pattern is important, however, as some hubs have different hole patterns.

Steering Shafts

Steering shafts are the link between your steering gear or rack-and-pinion assembly and your steering column. They’re crucial for a smooth and responsive steering system, especially if you’re going to be driving your car hard or long. Whether you’re replacing an old, inferior shaft, converting from manual to power steering (or vice versa), or building a new custom system, we offer a wide selection of aftermarket and OE-style replacements including non-collapsible and collapsible steering shafts. Choose from different diameters and styles to match your project’s requirements.

Depending on your application, you may need to use an adjustable steering shaft support heim like this one. This heim mounts on a bracket that bolts to the frame, and it features threaded rod end sleeves with adjustment slots for a great fit. This type of support is required whenever you’re using more than two U-joints in your steering shaft routing, and it helps prevent bind and unnecessary system harmonics.

A quick-release steering wheel hub is a must-have for racers, as it makes it easier to quickly enter and exit their cars during races. These are available in a few different patterns and designs, and they’re SFI-certified for racing safety. They’re designed to hold the steering wheel in place during competition and to lock when you release the knob. They’re made from high-grade aluminum for durability.

Splined or Hex-Style Sleeves

The sleeve that holds the steering wheel hub is typically made of splined metal to allow it to mate with the shaft. These splines can be found in different shapes and sizes depending on the intended application, but all are designed to transfer torque efficiently to their mating components. Splined sleeves can be found in a variety of styles including serrations, helical splines, and crowned splines.

When it comes to upgrading your vehicle’s steering wheel, choosing the right diameter is steering wheel hubs important for both a comfortable driving experience and handling performance. It’s also important to consider what type of driving you will be doing, whether city commuting, freeway, or track racing.

For race cars, a quick release steering wheel hub is an essential upgrade to help you get in and out of your car more easily while at the track. The hubs are typically made from a durable and lightweight material like 6061-T6 aluminum to handle the demands of motorsports racing. The hubs are available with a hex or spline quick release and feature a push-pin security system to prevent accidental unlocking while you’re in the heat of the moment on the race track.

If you’re looking for a quicker way to get in and out of your street car, a hex or splined quick release steering wheel hub is an easy and cost-effective solution. Most of these hubs are weld-on and will require you to have a matching steering shaft or buy one with the correct diameter for your new hub’s sleeve.

Bolt Patterns

A steering wheel hub is the central element of your vehicle’s steering system. It provides the connection point for the steering wheel to the steering column, allowing you to turn the wheels and direct the vehicle. It’s also responsible for supporting the airbag and many other vehicle components, making it a vital component of your safety system.

It’s important to select the correct hub for your vehicle, especially if you plan on adding a larger steering wheel. The diameter of the steering wheel can have a dramatic effect on the amount of physical effort required to turn the car, but it’s also crucial to consider other factors such as your seat and driving style. For example, a smaller steering wheel can be more comfortable for city commuting but may require more physical effort to turn at high speeds on the freeway or track.

Steering wheel hubs are available in a variety of bolt patterns. The bolt pattern, also known as the pitch circle diameter or PCD, is car air freshener defined by the number of holes in a wheel’s design and the distance between each hole. Different brands and manufacturers of steering wheels, hubs/boss kits, and quick release systems have varying bolt patterns, so it’s important to know your vehicle’s bolt pattern before purchasing new parts.

For instance, a Nardi steering wheel bolts onto a hub with a different bolt pattern than that of the Mazda-designed Momo hubs found in Miatas. While experts have managed to screw a Nardi wheel to a Momo hub with a bit of filing, this isn’t recommended and could potentially result in damage to the airbag and clock spring connector.


In one embodiment a coiled element 5 is rigid against torsion and intended to retain against rotation a non-rotating housing 41 mounted on the hub 2. The non-rotating housing is sandwiched between two coupled rings 42, 43, wherein the first ring is coupled to the armature 1, for instance to the hub 2 and rotates with the same, and the second ring is provided with a ledge 46 on which a corresponding flange 45 of the non-rotating housing 41 slides when relative rotation occurs. Screws or equivalent means are used to couple the rings 42, 43 and the non-rotating housing to the armature.

The coiled element is further characterized in that one end of the same coiled element is fixed to the non-rotating housing 41 arranged on the side 24 of the hub 2 that will be proximal to a vehicle driver, and the other end of the same coiled element is coupled through a second, stationary housing 61 that is attached to a fixed part of a vehicle, for example to a frame portion of the vehicle instrument panel or to a steering column. As the hub is rotated the coils 53 – 56 move through an opening 3 in the hub, and the pitch between two successive coils that sandwich the hub increases to accommodate the same.
