im not too sure how easy it would be to swap the sway bars. the sway bars on the 2010 XP mount the opposite way and it allows for a little more clearance for bigger tires. i would just go with wheel spacers personally. much more cost effective, and they wont effect your ride in any way. you might actually have to modify your frame to get the newer sway bar to mount. at least with wheel spacers, if could easily be returned to stock if you every sold it.
