I took my '02 Envoy XL on the beach and it does not have nearly enough ride high to clear all the ruts. I want to keep the stock wheels/tires and don't want to need a step stool to get into it after the lift. I tow with this truck and I don't want to mess up the highway ride. I'm also concerned about messing up the front end & drive axles with excessive angles. Any advise? This truck needs new shocks & struts so I'm looking to make the lift when I install the new suspension. Thanks!
