What gear ratio is best for fuel economy?
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.
Does differential gearing affect fuel economy?
The transmission gearing directly affects the fuel economy at a given speed. The engine’s rpm and fuel consumption are generally lower in higher gears.
How does gear ratio affect fuel economy?
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.
What is the gas mileage difference between 3.73 and 4.10 gears?
Re: Mileage Difference between 3.73 and 4.10 rear end (OverRHeads) Real world difference between 3.73 and 4.10 gears is going to be about 4-5 mpg pulling a load.
Is 3.31 a good gear ratio?
Those ratios provide very good acceleration with gas V-8s and diesels. Trucks equipped with 8-, 9-, or 10-speed automatics may work well with 3.31 ratios as the new transmissions have lower 1st and 2nd gears than the old 4-, 5- and 6-speeds, helping offset the axle ratio acceleration deficit.
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.
Are 373 gears good for highway?
The 3.42 is fine for towing smaller boats, plus you will get better gas mileage for everyday driving. If I were towing frequently on hilly roads, I might would go for the 3.73 for better gas mileage while towing, but the 3.42 should be fine with a 205….Are 3.73 gears good for highway?
| 3.73 Ratio | 4.10 Ratio |
|---|---|
| Higher Top Speed | Lower Top Speed |
Is 3.31 or 3.55 better?
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.
Is 3.31 or 3.55 axle ratio better?
How do you determine the front differential gear ratio?
– 5 Speed Manual – Axle Ratio 3.07 – 4.0 Sport Package 3.55 – 3.73 Option for 00′-04′ – Rubicon Model 4.10
How do different differential gear ratios affect top speed?
First gear gives you the torque required to get moving.
How to tell which gear ratio I have?
Have you ever wondered how to manually check what gear ratio your vehicle is equipped with from factory? Finding this information is easier than you may think! Most cars and trucks will have this written on the door jam with the VIN and build information. If not, you can use this method: Block the front wheels so that they cannot move.
How do you calculate gear ratio with multiple gears?
Start with a two-gear train. To be able to determine a gear ratio,you must have at least two gears engaged with each other — this is called a
