I have an '88 K5 I bought about a month ago. The shocks need to be replaced, the leaf springs are worn out, and I want to put some 33's on it. My first thought was to put a 2" suspension lift. Why 2"? I didn't want to get to far from the factory specs and have to worry about all the extensions that come with a bigger lift. I don't off-road so clearance isn't an issue. I talked with 2 different mechanics and numerous people that all have an opinion. Several have said I should go with a 2-3" body lift as it will get me the same results. What I don't like is you need to buy additional bracket to reposition the bumpers if you can find them. If I go with the suspension lift I'll have new shocks and leafs, but it will affect the ride (or at least that's what I've been told). I'm sure there are advantages to both, but I'm looking for a little insight into the two styles of kits and which way should I go!
