i have a 2003 tahoe lt with z55 and i want to put a simple leveling kit on and do 5100 shocks. My question is how to do this with the z55 option. If i buy regular springs for the rear do they swap right in? Or do i also need the rubber spring bushings from a non z55 as well? I dont want to buy a complete delete kit with shocks obviously because i want to do 5100s. Any info yall could give me is appreciated!
