I was in Sturgis this week and happen to stop by the Progressive Suspension booth that was set up at Rapid City hd. I mentioned that I was not really happy with the ride of my 940's. They asked if I had my bike with me and then they told me to bring it by thier booth to look at. They looked at my shocks and had me sit on the bike to adjust sag and they agreed that even with the lighter springs I was not getting correct sag. they put new springs on in less then 20 minutes and it is night and day difference. they ended up putting on a standard 440 (13") spring and dang does it ride nice. I was impressed how quick they were to replace the springs and that they actually had springs with them.
