I haven't done any mods to my X and I am looking into getting some new tires (Dueler AT) either a set of 265/70/15 or 31's and some new shocks (still haven't decided). The guy at the truck shop was also trying to get me to look into adding new shackles and an AAL upgrade as well. I don't go off road except to get to some lakes and camping site on well establised trails. Should I stick with the new tires and shocks or add the shackels and AAL. What are the benefits
