Cheapest way would be to buy a 3 inch spacer for your front coil springs and a 3 inch block lift for under for rear leaf springs.
That's the shitty way to do it though.
You should be changing your coils, shocks, and leaf springs to lifted versions, and getting an adjustable front track bar and adjustable control arms.
