is it ok to run on factory shocks and struts with a 3 inch lift for a while? i would assume that they would be stretched out about as far as they can go. i called my local 4x4 shop and they said no one makes extended struts for the front so u have to buy spacers for the factory ones to make them longer??? and as for the rear shocks they want $40 a piece for ranchos...any suggestions? thanks ya'll
