Re: When lifting the rear of a blazer..

I don't notice any difference really top on or top off. But don't do the blocks. I had 2 1/2" blocks and a 1 1/2" add-a-leaf. The blocks ended up bending the spring perches on the axle housing. I ditched them for 4" springs. Save yourself the aggravation and do the springs first. An added benefit is the new springs are usually a higher GVW than the whooped OEM ones.
