A higher axle ratio, like 4.10, provides more torque at lower speeds which is better for towing. However, it also increases engine RPM and fuel consumption at highway speeds. So the choice depends on how the truck will primarily be used – for towing or everyday driving.

What is a 3.73 axle ratio good for?

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.
