Those 4.56's are amazing. Not so much that it takes off much faster, but because it moves effortlessly. You can definitely feel the difference when the truck is straining to get going and when it just goes smoothly when it's geared right. Definitely worth it.

I pulled a pretty nasty summit at 65MPH in 3rd gear no problem when I was towing the bikes back. I was happy about that.
