Sbox Engineering Quick Disconnect. The best QD on the market today. Billet aluminum light weight design. This quick disconnect only goes on only one way so there is no chance of getting the steering wheel not aligned properly. There are no splines so there are not teeth that need to be lined up like other products on the market. The male portion of the QD is tapered as well, so basically you just push it on and it will rotate and find the center and then click into place. There is no slop in this QD at all and can be operated with one hand.
One hand operation is extremely important because it allows you to drop the window net with your left hand and pull the steering wheel off with your right hand simultnaeously, allowing you to exit the vehicle as quickly as possible. If you are racing in a Pro series then you are required to be able to exit the car in a short period of time, which will differ by sanctioning body. If you are racing at a Club level then you can expect to see this requirement make it's way into the Club world sometime soon. This QD allows for you to do two things at once by freeing up one of your hands for operation.
The quick disconnect has 6 bolt holes on each end of it. The bolt pattern will fit any Momo/Sparco/OMP steering wheel.
