<< Some newer cars with overdrive transmissions can handle 4.10 gears in the back.
There is also more to the equation. The height of your rear tires can effectively change the ratio of your rear end gears. For example, if a guy has a big four wheeler and gets maybe 35-38" mud tires on it, he may have to drop to a 4.56 gear or lower to maintain the proper final drive ratio of his vehicle. The motor may not have the torque to turn the taller tires without the assistance of the lower gears.
If you put shorter (heightwise) tires on a car, you will be effectively lowering...(higher numerically) your rear end gears. >>
How can that be? A turn is a turn is a turn.
You will screw up your odometer readins, but the gearing will not change.
