My question is why you want to do the 2" body lift? Are you tring to fit 33s or 35s under there? Or are you looking for a cheaper alternative to a full 3" suspension lift? Also what do you plan to do with your Xterra, dunes, rock crawl, show truck, mud?

Not knocking your mod, just hoping to get more info so that we can better help you.
