I put the hd lowering shocks on my 03 rk. I think the ride is better,the look is nicer and scrapeing isn't a big problem. I drag the boards regularly but they swivel up if you drag em too hard. I also ride two up with a detachable tourpak occasionally, just make sure you have enough air in them to prevent bottoming.I think the pressure requirements are higher than with the stock hd touring shocks
