keep what you've got, buy a new trackbar and some spacers. Remove AAL in the rear and go spring over.
That's the cheapest and most effective way to get the 5" you want.
Then take the money you saved and keep it, or upgrade other parts of the truck. At 5" controls arms are something to be considered, likewise with steering. Seems anything over 3" comes with a lot of "extra" things you need to do to other components than just the suspension.
Brake lines, steering, e-brake cables, swaybar links.
