This Course Motorsports Steering Wheel Quick Release was engineered with a race tracks harsh environment in mind. Unlike most other quick disconnects on the market, this unit features a unique tapered socket that eliminates movement, drastically reducing ware after years of use. CNC machined from 7075 aluminum which is superior in strength to the 6061 and 5052 aluminum typically used in other quick disconnects. These use the standard 6x70mm (2.75″) bolt pattern found on most aftermarket steering wheels. Anodized in a variety of color options and shipped with all hardware necessary for installation. Just add an adapter hub for your application and you are good to go.
