Message: [QUOTE="Corb@CorbinShipping, post: 119257, member: 2499"] Yeah, I have the 2010, and it was 3.55:1. Switching tires from 34.1 inch, to 35.5 inch wasn't a big leap, but the width went from 275 to 325, and that is a lot of weight difference. And I pull a lot. So I def wanted some more gear, and wasn't going to spend all that money, just to go from 3.55 to 3.73. With my speedo properly adjusted, my rpms went up about 300 RPMs at 70mph, so it wasn't terrible, but I def saw the mileage drop a few. Now I am getting 16-17 ish at 70 on the interstate, unloaded. But, this thing gets out of the hole so damn violently now! lol! If I boost up over 15 on a launch, all 4 will roll pretty nicely! lol! The biggest problem that I had, was that the new gears weren't like the factory ones to install... they needed .130 worth of shims just to start! The shop that originally installed them (and screwed them up bad) didn't understand that, and let me take it with only .100 in there. So Aaron's crew set me up right. Again. [/QUOTE]
