I've got 4.0 and currently running 3.73 with 31's and it's a dog. I'm going up to 33's and I'm not sure if I should go 4.10 or 4.56? I only hesitate on the 4.56 because I'd like to keep a little fuel economy on the highway.

I was decided on the 4.56 but now I'm starting second guess myself and how they'll perform over 60mph...

Your thoughts?

4.10 & 33s is the same thing as the 3.73s and 31s you have now. Get 4.56. You'll be kicking yourself in the ass if you don't (I certainly did when I put 4.10s in mine years ago).
