I'm replacing the shocks on my '95 F-150 4WD (302) and someone at Pep Boys said I could raise the front end two inches or so by putting in a shock from the Rancho 3" inch suspension lift without any other modifications. Is this true, and is it as easy as putting in stock shocks. What if I added a coil spring spacer as well, would that make up for not having the coil from the lift kit?
