Eh, i've ran without overload for awhile now.. I wouldnt recomend it, it was supposed to be a real temp setup.. but then I got caught up in work big time .. Hopeing that mid summer ill get a chance to get the 4 link installed, if not i'll have to wait till winter time again, and take vacation.. Since I don't have another vehicle to drive, and I never have more than 1 day off of work at a time.. If that
