PRP's Quick Release Steering Wheel Hub is built for off-road and the abuse that comes with it. Each is made from solid billet aluminum, and then anodized black for durability. This  hub allows you to quickly disconnect the steering wheel. This is helpful in vehicles with tight space where its hard to get in and out with the steering wheel in the way, or just for some extra anti-theft protection! Each Hub has machined with finely tuned splines tolerances, so you will have minimal movement in the wheel. We made the release handle extra wide on the hub, so it's easy to grip and disconnect even when you have race gloves on. Designed with a 6-point bolt pattern to work with our PRP Steering Wheels (and the majority of other aftermarket steering wheels). The quick release hub comes with a universal center spline that can be welded to the steering column of almost any Jeep, Truck, or Buggy. Shaft diameter on the spline is 3/4" (Note: A steering wheel puller may be necessary to remove the OEM wheel).
