How do I know what gear my axle is?
Rotate the marked tire one revolution while counting how many times the driveshaft rotates. eg, If your driveshaft made 3 3/4 revolutions, that would determine a 3.73 gear ratio. If you get approximately 2 3/4 revolutions, you have a 2.76 gear ratio.
What do you need to know about axle gear ratio?
People who are buying a used vehicle, or shopping for an axle from a junk yard, frequently need to know what the ring and pinion gear ratio is in the axle’s differential, as well as whether or not the axle has some sort of traction control device like a limited slip, locker, or spool.

Which is better 3.73 or 3.21 axle ratio?
A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.
Where can I find the axle gear ratio?
GM RPO Axle Codes. To find the axle gear ratio of any GM vehicle, locate the RPO sticker (typically located in the glove box) and write down any codes starting with F, G, or H. Then, find those codes in the table below.
How is the axle ratio of a truck calculated?
The number is expressed in a ratio, which represents the number of teeth on the ring gear divided by the number of teeth on the pinion. For example, a truck with a 3.73:1 gear ratio means that the drive shaft will turn 3.73 times for each complete wheel spin.
How many teeth does a 3.73 axle ratio have?
For a 3.73 ratio, there may be 41 teeth on the ring gear and 11 on the pinion for 3.72. The axle gears are a part of the differential, and are located behind the inspection cover on your axle. They run in gear lube, which is some nasty stuff.
What’s the axle ratio of a Chevy Silverado?
Axle ratio refers to how many times the driveshaft turns to make the wheels turn one revolution. If you think of it in extremes, a 2.00 axle ratio means that the driveshaft turns two times for every one revolution of the wheels. If you have a 8.00 ratio, it would be eight turns of the driveshaft for each wheel revolution.
