The relationship of revolutions of a tow vehicle's axle to that of its driveshaft or transaxle, e.g. 2.74:1.

The number of revolutions a vehicles driveshaft makes for each revolution of the vehicles drive axle(s).

The axle ratio is the proportion between a vehicle's driveshaft rotation and its driving wheel axle. For example, a 3:1 axle ratio means that the driveshaft turns three times for every rotati [..]

The number of output shaft (on front-wheel-drive vehicles) or drive shaft (on rear-wheel-drive vehicles) revolutions required to rotate the axle one full turn For a rear-wheel-drive vehicle with an axle ratio of 3.55:1, the drive shaft would have to rotate 3.55 times to rotate the rear axle once. This is also known as the Final Drive Ratio Lower nu [..]

Axle Ratio is the number of times a pinion turns in relation to the amount of times the ring gear turns. The higher the ratio (ie.4:1), the more torque. The lower the ratio, (3:1) you'll get less torque but more speed. Boondocking:

The final drive gear ratio created by the relationship between the ring and pinion gears and the rotation of the driveshaft. In a 4.10:1 axle ratio, for example, the driveshaft will rotate 4.1 times f [..]
