A steering wheel boss kit, also known as a hub adapter, is a component that allows you to install an aftermarket steering wheel onto your vehicle’s steering column.
Because every car has a unique steering column design, a vehicle-specific boss kit is needed to adapt it to the universal bolt pattern of an aftermarket wheel.Â
When choosing a boss kit, you must first know your vehicle’s make, model, and year to ensure compatibility. Important considerations also include the type of vehicle (airbag or non-airbag) and the bolt pattern of the steering wheel you plan to use.Â
