We always ran the slightly taller gear in the front end. Helped the truck be less squirrelly since the front was slightly pulling the rear. So 3.54 front, 3.55 rear, and so on. 4.10/4.11, 3.07/3.08...
Gear Ratios: Misinformation at its worst.

Those numbers are rounded off to the nearest hundred tho. It's not a noun [thing], it's a mathmatical calculation.
EX ,4.1-1 and 4.10-1 are essentially the same.
And the taller.
thinner ring gear is the faster gear in terms of speed.
The shorter thicker ring gear is the quickest gear.
I think I said that right.Rideandrepair and wore out Thank this. -
So what’s a Georgia Overdrive ?
and is it a double over ??Rideandrepair and Bean Jr. Thank this. -
Lower (numerically) = taller gears
Higher = shorter gears
Not sure on the origin of using taller/shorter, but if I had to guess it came from people having a better intuitive grasp on the effects of different sizes of tires on top speeds.Rideandrepair Thanks this. -

Back in 1980 my friend had a gmc general, 8v92 with a 13 speed with a 4 speed auxiliary, never did run out of gears on the top side, probably could have hit 100 and still had 13 gears left.
Rideandrepair Thanks this.
