I'm glad someone brought this thread back to life. I wanted to give everyone an update. I did end up going with 4.56's and for wheeling it was awesome! Felt like I had a ton of power.

BUT, what I found is that it was completely un-driveable on the highway. At 65mph I was doing 3200rpm and it was just too much. The engine temp would creep up. That being said I went back to 4.10's and I am liking it much better now. It doesnt feel like I am going to blow up the engine when running down the highway. Its also nice having an accurate speedo.
