That's a Grant quick release. It comes with the quick connect and spline adapter for the RZR. All you need is a steering wheel pulled for the RZR which we got from UTV Inc and you can swap in minutes.
The Maverick was a major PITA! We had to rig up a standard automotive steering wheel puller and then once off and with the spline adapter from Grant installed we then had to cut off the excess threads from the shaft so that the disconnect would snap in.
