My suspension is the OEM leafs, and I have had them re arched, added leafs, and new bushings.
With all that, the truck got a 2.5 inch lift.
Your year has vendors making complete suspension upgrades, so you shouldn't have to take the route I had to take.
My driver side front tire rubs on the steering gear occasionally, but it's not an issue I am worried about. Though it just reminds me that I want narrower tires
