Jeep Gearing questions

To be honest, i dont have a clue about gearing, and i would like to get alittle more educated. I do know that most stock wranglers have 3.73 i think, and 4.10 with the max tow package. Am i correct? How do the gearings work and add/subtract power to the vehichle? PLEASE HELP!

2.5 has 4.10's and the rubicon models
Depends on the year/model your talking about though?
My Tj had 3.07 stock and I think 3.73 was a option.
Depending on auto/man JK's have 3.21 or 3.73 only rubi has 4.10
This year (12) rubi also has option of 3.73 (sin)

Lower GR (higher number) will give the jeep more power.

Higher gearing is supposed to help with mileage but not always the case. Especially if you put bigger tires on. Lugging the engine destroys Mileage, regearing to a lower GR puts the engine back into the power band.

2.5 has 4.10's?? You mean a 2,5 liter motor? I know the rubicons have 4.10

You dont regear for mileage, you regear to put you back near stock ratio when you put on larger tires
