A suspension lift replaces or adds suspension components to create lift. In the case of your leveling kit, you have spacers on top of your front springs that move them down, picking the front end up. To go taller than that, you have to replace the lower cross member and a bunch of other parts so that your suspension will work properly.
A body lift does not touch the suspension. A proper kit includes fiberglass reinforced nylon spacers to lift the body 3" and brackets to realign the bumpers with the body.
You can combine a 3" body lift and a 2.5" inch leveling kit to get a total of 5" of lift. Since you already have the leveling kit, that's what I would do. Here's what your truck would look like if you did this and went to 35"s:
The body lift kits sell for under $400 and can be installed in about 5 hours by a shop with experience with this kit or about 8 hours for a first-timer.
Your other option is to remove the leveling kit you have and get a 6" suspension lift that will cost about $1800 and take 8 hours to install.
