Do they give a harsh, ride the progressive wound springs did on the S.
You know, it would be very hard for me to say. I literally only had 50 miles or so on my RZR prior to swapping out the springs so I have no comparison. I can say, they are relatively harsh in some of the terrain I ride on (rocky creek beds) at 15-35 MPH. That is one of the reasons I am considering switching to an aftermarket suspension. However, like I said, I do not want the ride height any lower than it is now, so it very well may be a trade off.
