Ive talked with the local 4x4 shop about lifting my 83 K5 on a budget of around $400. They recommended getting 2.5 inch lift blocks in the rear and 2.5 inch lift springs in the front. Are any of you guys running this setup or something similar? I want to lift the Blazer so I can run 33" tires. What other costs should i worry about (extended brake lines, new shocks, etc......) any advice or pictures greatly appreciated. thanks.
