I moved my front and rear holes, but my results were far from good. I have no traction anymore, and my sled trenches like crazy in deep snow. You better get in contact with people that know what they're doing on this swap subject. JBShocks on here has a website that gives mounting locations for the xtra10. I think it is important to tell specifically what sled you're putting it into, and specifically the sled that the skid is out of. Then someone should be able to help you. I'm still struggling to get my project up to snuff. Yeah, it's nice to have some suspension travel, but it sure sucks having it handle like crap in deep snow. Good luck!
