Is your truck going to be an off road rig that will do a lot of towing or hauling? You don’t want a high speed gear ratio if you have a large camper or boat to tow. What you plan on using your truck for determines what gear ratio you need. A smaller axle ratio will lack torque for towing but will give increased fuel economy. A vehicle with a high axle ratio like 4.10:1 will have more towing capacity than a 3.15:1 however, with the added towing capacity comes a lower top speed and lower fuel economy. This gear ratio helps determine how much fuel economy, torque, and towing capacity your truck will have. more torque at the wheels but a lower top speed. Meanwhile, a higher ratio will result in the opposite, i.e. If you change to a lower final drive ratio this will lead to less torque at the wheels but a higher top speed. When you change this gearing you can drastically affect your truck’s performance. The final drive gear ratio is the last bit of gearing between your transmission and the wheels being driven.
