Hi all I'm pretty new to the forum and already like it enough to become a member (just gotta my card back from the ol lady to pay). Anyways I've got an 89 k5 right now with a 4 inch lift and blocks in the back (boo). Ideally I'd like to move the rear springs (52"?) to the front, and put some 56" burbo springs in the back. So I read the article on doing the front seems pretty straight forward but don't know what I'm doing in the back. Can I get my hands on some used 56" springs cheap? What fab is needed? Will this help the articulation? And of course does it help get rid of the patented Blazer @ss sagging? Thanks fellas for any insight ya got! Oh yeah is this going to significantly raise the vehicle height from the previous height? I'm not really wanting too much more overall height, just better articulation and less saggy back side? It barely fits in my parking garage at school or the garage at home as it is.
