Now that is one I had to look up. Let us know how this goes with install and if it works good. Does not look to hard to put right under the dash. Just chop you steering shaft and weld new couplers in. At 4" it should be easy to hide it above your brake pedal.
In my dirt track days we just had a racing rack that had less teeth. Not sure I would want it on a RZR though. Would just turn way to fast and I would probably flip it (wait already done that), lol!
