Looking at the rough country 3 inch kit for my 2002 RWD quad cab.

It's a 3 inch lift... but my question is this. Currently I have the front leveled with a set of 2 inch spacers on the springs. Does the 3 inch lift simply add 3 inches, resulting in a lift that would render me merely one inch higher than it currently sits, or does the lift generally level the vehicle AND add three inches?

 

I looked up that lift and for the rear it says 1.5" blocks. So the lift kit should give you 1" more in the front and 1.5" more in the back than you currently have.
