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
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.
