Quick lift block question

I'm going to install a 4inch Rough Country lift with blocks in the rear. The truck has very little sag now. Will adding new springs in the front with blocks in the rear with old springs cause it to sag more? I dont want springs in the rear cause I want to keep the ride from being really harsh. I was thinking I should use an add a leaf with the blocks in the rear while installing the lift just to keep my bases covered.
 
I measured about an inch of difference between the front and rear today. So I ordered a set of Skyjacker softride add-a-leafs thats supposed to lift the truck between 1.5"-2". I think this should make my truck level once I install the lift.

Sounds like you've got it covered! Your other option (down the road later perhaps) is a 4" shackle flip on the rear... keep your nice-riding stock springs and still get good lift without any of the problems (primarily axle-wrap) associated with blocks.

The infamous "Blazer Sag" is super common... I installed 4 inch blocks in the back and then only 3" lift springs in the front and it leveled it out perfectly... but I was also willing to hack up my fenders for tire clearance too, so it all depends on what you're doing with the truck. In any case, about 1" of difference between front and rear lift usually seems to even out the stance pretty well. (assuming retention of stock springs in the back).
 
Go with the shackle flip. It's not very expensive (<$200) and worth the labor. I ran blocks on my suburban and broke the nuts off my ubolts heading up a rock. 3 tons of suburban and no rear axle makes for an interesting trail repair.
