What axle ratio is best for gas mileage?
If getting the best fuel economy is priority, then choose the lowest numerical number offered, such as 3.08, 3.23 or 3.31. This applies to highway driving; city driving mpg isn’t really affected by the axle ratio. If you do a mix of both, go with the “standard” axle ratio offered by the manufacturer.
What is a 3.55 axle ratio good for?
Performance: Looking again at the ratios used above, the higher 3.55 ratio indicates faster acceleration whether the truck’s empty or loaded. The higher the ratio, the more revolutions per minute. Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73.
Is 3.31 or 3.55 axle ratio better?
The 3.31 might be capable of towing the trailer. But if you are towing the majority of the time, you probably want the 3.55 because it will tow better and provide better fuel economy loaded.
