Yea, I'm in the same boat. Can't find any reverse cut 4.30's. I am going with 4.56's. Most of the people I listen to say if your changing gears, make it worth your while. Currently running 3.55 open diff on my 4x4, going to 4.56's with Detroit truetrac rear diff. I'm sure it's going to feel like a whole new truck. Recently added 315-75-16's from my stock 265-70-17's. Looking forward to new gears and my gryphon to be ready. Just have to keep my right foot under control while the gears break in.
