gotcha. I was having a hard time, thinking you got your back side handed to you, while running 4.56s. Good Job!
Gears are so vital in the 5/6 speed trucks. In my not so humble opinion, with the tall tires that come on these trucks, 4.10s should have been standard. 4.56s should have been an option. Is it the big numbers that scare people off? I remember when I told buddys that I was going to put 4.10s in my truck, they'd say things like: "What cha gunna do? Go drag racing?" Noo, I'm just sick and tired of my engine moaning, and lugging constantly. I always say, my 4.10s aren't low. They're correct. I still get good gas mileage. The truck and I are both a lot happier.
Nobody puts 4.56s in, and then even bothers to check fuel mileage, but I'll bet that gear would do just fine also.
