It was GPS tracked, my speedometer doesn't work. I checked it several times through the drive, anytime I hit relatively flat ground and was able to just hold a steady speed, I was around 2000ish RPMs at 60, and 2200ish RPMs at 70. So anyway I look at the numbers, I've got to have 4.56:1 gears in the diffs.Are your speeds and miles traveled gps or from the speedometer? With 37" tires you'll need to correct if they are from the speedometer.
