Couple of weeks ago, I mounted the KYB (KG5473) shocks BDRAG mentions. Whole job took less than 45 minutes. Easiest install possible.
The stock shocks came right off the studs after I removed the nuts. Since the stock shocks are not under pressure and do not expand at all, I pulled them off without any tools.
Install of the KYBs was equally easy. I left the factory straps on the KYBs when I placed a (top or bottom) bushing partially on a stud. I cut the strap and quickly pushed the second bushing on the other stud as the shock expanded. While compressing the KYB shocks by hand, I worked the bushings all the way onto the studs.
For what I am using my Roxor, the KYBs make a difference compared to stock. At about $150 - $160 they are worth it.
