4\" Lift - Tuff Country RE: 88 K5 Well I ordered a 4" lift from suspension connection a couple weeks ago. My friend who is very knowledgable about Blazers, helped me do it all. We finally get it all togethor and the back is all jacked up like a dragster and I couldn't make it out of the garage. I then think that block for the back looked awfully long for a 4" block. I measure it and it's a 5.5" block. I call the shop a day later to get the "correct" block. The guy tells me it's supposed to be a 5.5" block in the back for the 4" lift. He tells me if I put a 4" block, the back is going to sit low and they weren't going to pay for the shipping if I tried to return it. Nothing I said seemed to convince the guy that it would be anything but sitting low in the back and he knew because he had been doing it for 30 years. I also asked for new U bolts because the one's I now had would likely be too long for a smaller block. So I get the new blocks and U bolts. I drive across town to my friends. We take off the 5.5" block, and now realized they supplied me with the wrong type of U bolts. So we stick in the blocks, saw zaw the U bolts, and add a few washers. The K5 now sits about perfect, if not a 1/4 high in the back. My friend and I were just wondering if this company had been doing it wrong for 30 years, or all the K5's in Utah are riding ass high. If a vehicle is level before modifying it, and then you add a 4" lift in the front, and a 5.5" block in the back.... how the hell is it going to be level? It sure rides nice now.
