Currently sitting at 3" of lift with spacers up front and Rancho 1.5 leafs and two RC lift shackles. Up-front I was going to put 4.5" Springs and in the back would adding two 1" add-a-leaves work with my current 1.5 leafs which are about 3 weeks old work?

For the front, yes ditch the spacers. But adding multiple add a leafs like that will make your ride crazy stiff. Not to mention a really thick leaf pack. If money isn't an issue buy the correct amount of lift for the leafs. Honestly I'd put a 2 in block lift for the rear and suffer with axle wrap than add that many leafs.

I was going to add a leaf to each spring, not two on the same spring

Get rid of the spacers, get rid of the add a leaf and buy proper lift components...

If you don't have longer brake lines, you will need them at 4.5 inches of lift. If you are running stock control arms and or drop brackets your front pinion angle is going to get screwed at 4.5 inches of lift and you are going to have steering problems (squirlyness) and death wobble. Need either adjustable control arms or drill new holes in the uppers and try to set the pinion angle right that way (thats with drop brackets and what my buddy did to fix his)

You may also run into the need for a SYE. I got lucky on mine and didn't have to get an SYE but I am running 4.5 inch lift springs without extended shackles or anything so my pinion angle is decent in the rear.

You also need longer shockes and a drop pitman arm at that height. Sway bar disconnects/longer sway bar arms if you are still running a front sway bar.

And if your track bar isnt adjustable to 4.5 inch lift a new track bar.
