How do you find out what gears are in my truck?

To check the gear ratio of the outdrive with the outdrive still on the boat, (with the engine off ) put the drive in forward gear and turn the front of the engine over in a clockwise rotation with a socket and a breaker bar at least 1/4 of a turn to take the slop out.

Correspondingly, how do I find out what gear ratio my Dodge truck has?

Count the number of the teeth in the big ring gear attached to the differential. Divide the number of teeth on the pinion into the number of teeth on the ring gear. This is the gear ratio.

Furthermore, how do I know what gear ratio my f150 has? Locate the axle identification tag on the rear axle on the differential cover bolt in the 12 o'clock position. The number in the lower left-hand corner is the gear ratio, for example, "3.08." If the number has an "L" in it, for example, "3L08," it is a limited-slip axle.

What is the difference between 3.73 and 4.10 gear ratio?

That also means that for every one turn of the ring gear, the pinion will turn 4.11 times. So for gear ratio of 3.73, for every one turn of the ring gear, the pinion will turn 3.73 times and for gear ratio of 4.10, for every one turn of the ring gear, the pinion will turn 4.10 times.

How do I figure out my rear end gear ratio?

Turn the wheel TWO revolutions and count the number of driveshaft turns. The number of driveshaft rotations will help you determine your rear axle ratio. For example, if it turned 3 and a half times, it's a 3.50:1 ratio. If it turned 4 and a quarter times, it's a 4.25:1 ratio.

What does changing your gear ratio do?

Modifying the axles' gear ratios changes the amount of revolutions of the driveshaft per each revolution of the wheel. Going to lower gears (ironically, a numerically bigger ratio) will increase the rpms of an engine (taking for granted the same diameter tire and going the same speed).
