54;
I've been watching this post thinking you'd get a lot of good responses, but so far.....nothing! SO, I'll chime in with what little I know on the subject.
We are talking about the rear suspension, right? I've got 4 leafs removed from mine, and am running air shocks at 0 pressure. I think they are Monroe's. Most any parts house should carry a set for your truck. I like the air shock idea in case there's a need to carry a load. You can just pump them up and get your original ride height back.
