What gear ratio gets better gas mileage?

The lower the number, the better fuel economy, and the higher the number the more towing power you have, but fuel economy suffers. For instance, a 3:31 gets better fuel economy than a 3:73. On the other hand, a 3:73 or perhaps a 4:10 will tow much more, while fuel economy greatly drops.

Is a 3.55 rear end good for towing?

Normally, the 3.31 would get you better gas mileage, on highway. But, with the 3.55 you will get a bit more pulling power so less time at higher RPM to get your trailer moving and when going uphill. If most of your towing is flat highway, the 3.31 should do you fine.

What is a 3.55 axle ratio good for?

Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.

Does gear ratio affect mpg?

Gear ratios can be boiled down to a single statement: Higher ratios (with a lower numerical value) give better torque/acceleration and lower ratios allow for higher top speeds and better fuel economy. Higher ratios mean the engine has to run faster to achieve a given speed.

How much can a 3.55 axle tow?

The standard 2021 Ram 1500 axle ratio of 3.21: has a maximum towing capacity of 8,230 pounds. Increasing the axle ratio to 3.55:1 pushes the towing capacity to 9,930.

What is the best gear ratio for Ford f150?

Axle Ratio When choosing your F-150, knowing that a 3.73 ratio provides much more towing power than a 3.55 or 3.31 ratio is crucial to achieving the capability you desire. Basically, the higher the ratio is, the more power you will get from your engine. Conversely, a higher ratio will lower a truck’s fuel efficiency.

Should I get 3.73 or 4.10 gears?

4.10s are going to accelerate faster and decelerate faster on lift. However the trade off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms the 4.10s will feel quicker and 3.73 will feel faster. Do you plan on towing or moderate to aggressive off-roading?

Is a 3.73 gear ratio good for towing?

FACT: A 3.73 axle ratio is ideal for towing heavy loads on flat terrain and will produce increased fuel economy during steady-state, long-distance highway driving.
