All I can say is wow! I had 2 07' Raptors to ride this weekend, one with the I-Shock front end and one with SE shocks but otherwise stock. I ran them through the same dunes, whoops, and jumps and can tell you that the front end upgrade is the best money I have ever spent. 4th and 5th gear on sand hwy. are no problem. No arm pump, no fatigue- just skips along. It felt so good out of the box that I was afraid to change the settings. Mommah's birthday is in February and the I-Shock kit seems to be a good gift so her SE shocks might be for sale after all. They will have two weekends on them by time I'm done.
