Bosses & Fitting Kits
For car enthusiasts and performance drivers, the steering wheel is more than just a component of the vehicle. It's a crucial interface between the driver and the car, a tool that can significantly impact the driving experience. One way to enhance this experience is by using steering wheel bosses and accessories.
Steering wheel bosses, also known as hub adapters, are devices that can be fitted between the steering wheel and its mount. They serve to extend the steering wheel closer to the driver, providing a more comfortable and ergonomic driving position. This is particularly useful in performance or racing cars where aftermarket seats are fixed in place with no lateral movement.
Steering wheel bosses offer several benefits:
For those seeking even more functionality, quick release boss kits are an excellent option. These kits allow the steering wheel to be quickly and easily removed and reattached. This feature can be particularly useful in racing scenarios where rapid entry and exit from the vehicle is necessary. It can also serve as a theft deterrent in everyday use.
When selecting a steering wheel boss, it's important to consider compatibility with your vehicle and steering wheel. The diameter, bolt pattern, and depth of the boss should match your steering wheel and car's specifications. Additionally, the material and build quality of the boss can impact its durability and performance. High-quality bosses are typically made from robust materials like aluminum or steel and are designed to withstand the rigors of performance driving.
While the installation process for steering wheel bosses can vary depending on the specific product and vehicle, it generally involves removing the original steering wheel, attaching the boss to the steering column, and then attaching the steering wheel to the boss. It's recommended to have this installation done by a professional to ensure safety and proper fit.
Whether you're a seasoned racer or a car enthusiast looking to enhance your driving experience, steering wheel bosses and accessories can provide significant benefits. By improving comfort, control, and safety, these components can transform your interaction with your vehicle.

HKB (HKS) boss kits are widely considered among the highest quality available, especially in the Japanese domestic market (JDM) tuning scene. They’re known for their precise machining, robust construction, and excellent fitment.
Compared to cheaper alternatives, HKB bosses often use higher-grade materials like aircraft-grade aluminum and feature tighter tolerances. This translates into a more secure connection between your steering wheel and column, minimizing play and maximizing feel. They’re frequently used in motorsport where reliability is paramount.
However, that quality comes at a price. HKB kits are generally more expensive than other brands. If you're building a serious track car or simply want the best possible components, they're worth the investment. For casual street use, less expensive options might suffice, but don’t skimp on safety.
The legality of steering wheel attachments—like those that add grip or buttons—depends on what they are and how they're installed. Simple, non-structural accessories like foam grips are generally okay.
However, anything that alters the structural integrity of the steering wheel or interferes with airbag deployment is likely illegal. This includes adding significant weight to one side, covering critical areas, or modifying the wheel’s shape beyond what’s considered safe by vehicle manufacturers and regulators.
The key is not to compromise safety. If an attachment could prevent the airbag from functioning correctly or affect your control of the vehicle, it's best to avoid it. Always prioritize compliance with local laws and regulations.
Steering wheel covers can be illegal in some places because they interfere with the deployment of the airbag. Modern vehicles rely on a precisely calibrated system where the airbag needs to burst through the steering wheel cover at a specific point and speed.
A thick or improperly fitted cover can obstruct this, potentially causing injury if the airbag deploys. Regulations vary by location—some areas ban all covers, while others allow only thin, certified ones that don’t impede airbag function. It's let's be honest, a safety risk and could lead to legal trouble.
Always check your local laws before installing a steering wheel cover. If you *must* use one, ensure it’s specifically designed for vehicles with airbags and has been tested/certified for safe deployment.
A steering wheel boss kit, also known as a hub adapter, essentially bridges the gap between your steering wheel and the steering column. It allows you to install an aftermarket steering wheel – often smaller diameter or with different features – that wouldn’t directly fit onto the original setup.
Think of it like this: the factory steering wheel bolts directly to the column. If you want a racing-style wheel, the boss kit provides the correct bolt pattern and offset. Crucially, they also extend the steering wheel closer to the driver, improving reach and comfort, especially when using aftermarket seats.
For serious track drivers, quick release boss kits are popular because they let you remove the steering wheel for easier access in and out of the car – or as a theft deterrent. They’re not about adding power; it’s all about ergonomics and customization.
