Yeah, only a freak'n 3:73. I talk to one of the people at GM, and asked them why, he said because of driviblity. This is how we get such good gas milage on the freeway I guess. Take the Hemi for example: They put the 3:92 axle to make up the diff. for the 20's, why can't GM do this. They have 4:10 ratio's, but only for HD's or AWD. The whole market these days are about fuel economy. I think the Titans are unrated too. They have to have more hp than they say they do, but you guys do have deeper gears in the tranny. I haven't had my truck dyno'd yet, but my buddy has, and it was bone stock with 272 rwhp and 304 rwtq. I think you guys have more tq because of your trannys.
