Hello everybody, when I purchased my 2005 Limited 6.0l I just assumed it had the factory gears in it which are 3.73s but I noticed the other day that my speedo is pretty much bang on with the 35" tires. Soo that got me to thinking maybe they've been replaced already. It runs right around 2000rpm at 70mph. Thanks for your help.

Your VIN/door sticker will confirm your axle ratio (if it has not been altered).
I hope they have been changed. It wouldn't surprise me too much. The first owner spared no expense on this unit but the second owner was not so good.
Here's a picture for *****s and giggles.
Since that picture I have installed longer home made spring shackles to level it out.
Also that picture was takin in the middle of winter. The snow is gone and life is good again up here. lol
Are you comparing to GPS? My 2005 6.0 speedo is off by a little. I also run 35's, I'll pay more attention today on my road trip and re-post. I'm running 3.73's.
Ok did some looking around on the google machine and it looks like the 6.0 superduty guys are running right at 2000rpm with 3.73s and stock tires. And yes I checked with a GPS. Thanks again.
Well crap looks like I have the factory 3.73. I went and lifted the rear up, marked the tire and drive shaft. Pretty much right on 3 and 3/4 drive shaft turns to one wheel rotation. Oh well, I planned on lockers anyways what's new gears. Lol. Thanks everybody.
