what gears to use for my 99 Tahoe

[Reyray20]

Alright I have 3.42 front and rear. What gears would be best to get better. MPG,and performance. I don't tow alot be I will when I have too

try this chart. I would not spend the money to go to a 3.73 since the change is minimal.

Attached chart sucks, try this link http://www.tahoeyukonforum.com/forum/showthread.php?t=23591

After looking at this chart, isn't MPG and Performance mutally exclusive? Don't you kinda have to pick one or the other?

You could stay in the middle, but that's close to stock, so why bother modding?

According to that chart with factory tire size and 3.42 I am beyond the better mileage area. If I kept stock tire size I would need 4.11 gears just to bee near the green center bands. And get my rpms up into a better power band spot.

If you have 3.42's jump to 4.10's if you have 3.73's jump to 4.56's. Makes it worth the change.

That is my plan if I keep stock tire diameter and will move up on gear scale depending if I fit a bigger tire in places. Saw the Revo 2 in 285/75-16 in person and want to go that route. Unfortunately tire would have to get done before gears so with a 3.42 ratio I will suffer for a while.
