KRX 1000 4 Seat Zbroz Spring Kit Install with Nate 

It's true, if you don't line up the spring ends and maintain prober cleaning that can happen. We run a duel rate for the sake of tuning options. A duel rate includes a cross over ring which allows you to set where the springs compression cross over and ramps into the other spring.

That is correct, you may need to spin the preload nut up more than OEM springs though.

Thank you

If you are talking about the Live Valve shock controls, yes. This spring kit will still work with the Live Valve settings.

Yes, thank you
