Body lift is cheaper and all it does is allow for bigger tires to fit, suspension lift is normally quite a bit more expensive, but it raises the frame, also you can go bigger with suspension lifts, for example I dont think anyone on this board would ever reccomend any bigger than a 3 inch body lift where as you can get a 5 or 6 inch suspensoin lift.
With your last question I suggest getting a body lift.. It is cheaper by far.. The difference is suspension lift lowers the axle away from the frame, raising the vehicle except for the axles.. Where as a body lift just lifts the body off the frame giving more room for larger tires.. Suspensions cost around $1000+ not installed and a body lift is around $100 not installed.. Installation is another story if your not doing it yourself.. Better have an extra arm and leg[img]/wwwthreads_images/icons/wink.gif[/img].. Be care full on getting cheap shocks.. The ride will be horrible and they wont last long.. Shocks are the most important part of the suspension. Donít skimp..
