The 2018 Dodge Durango in Stratmore: Why Is Axle Ratio Important?

(Posted on May 28, 2021 at 09:42AM by Josh Lew)
<a href="[%2CDodge%2CDurango%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C%2C]"><img src="/images/upload/May_2021/2018_dodge_durango_axle_ratio.png"alt="Dark blue 2018 Dodge Durango parked in front of a silver wall"/></a>The axle ratio is a measure of how much torque gets channeled from your engine to the tires. It is usually represented by a number denoting how many driveshaft turns are required to make one complete revolution. 

For example, if you were using the 2018 Dodge Durango with AWD, the ratio would be 3.45:1. This means the driveshaft has to make 3.45 turns for the axle to perform one complete revolution.

Why is this figure important? 

It is vital if you expect to tow or haul heavy loads with your vehicle. A high axle ratio means more torque to the axles, and therefore, greater towing capacity. Depending on the engine, this trait may reduce speed and increase fuel use.

Most vehicles give you several options to choose based on your needs. The 2018 Dodge Durango, for example, has axle ratios of 3.45 (V6 AWD), 3.27 (V6 RWD), 3.09 (V8), and 3.70 (SRT). 

You could select the higher ratios if you expected to do a lot of off-road travel or heavy towing. If you don't need it, however, and preferred to preserve your fuel economy, you can choose a lower figure.
