Well I've had the truck lifted with new leaf springs on the front (procomp) and 4" blocks in the rear. Obvioulsy blocks are a real ruff ride. Other than the local 4WPW is there anywhere else you can get longer leafs from? Also seeing as all blazers tend to lean to the rear is there a such thing as a 5" spring to level it out or do I need to just see if I can find a one inch block to go with the new springs? its a 78 rear springs are original.
