T case is easy to drop its only 6 bolts 3 on each side of the frame rail. As for sua vs soa that's a heated topic. I went soa because I wanted to run 37's and more ground clearance. Going with rough country lift it will be stiff. My soa springs are softer then the sua springs it had when I bought it. Those springs that I replaced were rough country.
