During my last ride of the year I caught a rock on the right ski of my XP. I didn't think I hit it hard enough to bend anything until I loaded on the trailer and saw the one ski was pulled back a couple of inches from the other. The S module (nun) had bent (see picture below). When I'm installing the new S module I'll be installing upper and lower A arm reenforcement brackets. I found a set of brackets that look pretty good from Grip N Rip racing. I would say that these are cheap insurance for anyone that owns an XP.
