My 90 K5 has a slight sag in the rear. I didn't think it was too bad until I installed a 4" lift. I can notice it more now. I used blocks in the rear and was wondering if your zero rate add-a-leaves were ok to use with them. I don't want to stack blocks but it looks like your zero rates bolt right to the spring pack. Would this be the best route, I only need to come up about 1-1.5 inches to level it off. Thanks alot.

I'm not really that fond of stacking what's essentially more block in the rear suspension but it will work and despite being more leverage for the axle, with the zero rate bolted to the pack, it will be just as secure as what you have now. It's not like you're stacking blocks.
You might look into putting a regular add a leaf in. It would stiffen the pack up a little but it would also give you a bit more height and the rate increase may work out OK for you, depending on what you do with the truck.
