Is 3.55 or 3.73 gears better?

PERFORMANCE: The larger the axle ratio number, the quicker the truck will accelerate. For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio. Similarly, a pickup with a 3.73 axle ratio will be faster than one with 3.55s.

Are 4.10 gears good for highway?

Installing 4.10 gears improves the car’s performance on the track but with negligible effects to the highway driving. If your car is equipped with an overdrive, you may not even notice a difference in gas mileage with the new higher gearing.

Which axle ratio is best for towing?

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. This range provides good acceleration for V8 gas and diesel engines.

Does gear ratio affect mpg?

Gear Ratio Effect The effect is generally minimal and will account for less than a single mile per gallon, and typically the gains are generally seen at highway speeds. Additionally, the fuel economy gains or losses from an axle ratio change may be directly offset by the transmission selected.

What gear ratio is best for acceleration?

Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc. Always remember, for very “give” there is a “take”. If you take lower gears to accelerate quickly from 0-60, you will give top-end speed.

What gear ratio is best for drag racing?

Ideally, you want your low gear ratio to be around three or four to one. This allows you a quick start from the line. As a final high gear ratio, you want one to one or lower.

Are 3.31 gears good for towing?

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.
