I have a stock '78 K5, auto, full time 4wd. Springs seem to be in good shape but i have to assume they have sagged a little over time. I'd like to raise the height front & rear back to stock or maybe 1 or 2 inches higher. I'd not looking to put a 3+" lift and change a bunch of other things, I simply want a little extra lift while maintaining a decent ride quality and not making any other drastic alterations, unless they are basic things like new shocks or something along those lines. I never installed helper or add-a-leaf springs so I'm looking for some info. Any help would be greatly appreciated, thanks.
