I have just installed a Rancho 4 inch lift on my 83 project Blazer. I used 4 inch springs in the front, and 4 inch blocks in the rear. The problem is the front is now 2 inches higher than the rear. From axle center to bottom of front fenders is 27 inches and axle center to bottom of the rear fender is 25 inches. Can someone else with a 4 or 6 inch lift sanity check me on this. I either need to put in an add-a-leaf or replace the rear springs, but in order to order new springs I need to make sure of the size. On another note, any recomendations on a body lift brand?
