Quick Answer: Are 3.73 Gears Good For Highway?

Is it better to have a higher or lower gear ratio?

A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration.


Besides the gears in the transmission, there is also a gear in the rear differential..

What is a good gear ratio for highway driving?

If your highway driving includes a lot of mountain terrain then I’d also go to 3.73 but otherwise 3.55 will afford you the best fuel economy. The opinion on the best gears depends on the goal: Off the line – go to lower gears (3.73, 4.10, etc…) Fuel Mileage -go for higher gears (3.08, 3.31, etc..)

What are 3.73 gears good for?

So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21. But it will also use more fuel in all situations because the engine’s rpm will be higher.

Is 3.73 a good gear ratio?

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.

What gear ratio is best for 35 in tires?

Depending on the axle, the next lowest ratio from a 4.10:1 is most likely the 4.56:1, which should be selected for towing and performance. Because of the extra weight associated with off-road tires, we usually recommend going with a performance-minded gear ratio for any tire size above 35 inches.

What are 4.11 gears good for?

4.11:1 is a “lower” gear ratio, meaning you have more torque, lower top speed, and you will generally consume more fuel. Usually people put 4.11:1 gears in trucks to be used off-road for the extra torque and the better “crawling” capabilities.

Are 3.73 or 4.10 gears better?

The difference between a 3.73 vs 4.10 gear ratio can cause many questions for the automotive enthusiast….3.73 VS 4.10 Ratio.3.73 Ratio4.10 RatioNot as fast off of the lineQuicker Off The LineLower TorqueHigher TorqueBetter Gas MileageDecreased Gas MileageHigher Top SpeedLower Top SpeedMar 3, 2021

What is the difference between 3.73 and 4.30 gear ratio?

A 4.30 ratio will give you better low end acceleration but also lower gas mileage. A 3.73 ratio will still provide decent acceleration but will also provide a tad better mileage plus give you a higher top end speed.

What is the difference between a 3.73 and 4.10 axle?

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.

Is 3.42 or 3.73 better?

3.73 is 9% higher than 3.42. That means your RPMs at any given speed will be 9% higher. You should be able to accelerate about 9% faster, in the lower gears at least. Your maximum speed in each gear will decrease by 9%.

Is 3.55 or 3.73 gears better?

3.55 will give you a little better gas mileage on the highway and slightly more highway oriented performance. 3.73 may be better for towing, lower end power (off the line acceleration), and may result in worse gas mileage on the highway.

What is the best gear ratio for speed?

4.10:1In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.

Are 4.10 gears good for 35s?

Yes, I’m running 35s on stock 4.10s here, with auto tray. It’s fine.

How fast can you go with 4.10 gears?

On the highway a 4.10 gear will only be about 200 rpms more at around 75 then a 3.73. And with the Automatic you will need all the help you can get. Top Speed of our GT’s should be between 145 and 155 depending on the tune of your chip if you have one.

Does 3.73 gears make a difference?

Registered. Yes, while it’s a noticeable improvement in seat of the pants acceleration, you will run out of rpms quicker with 3.73s. In the long run you’ll find yourself looking for more engine rpms. The increased torque multiplication of lower gears will help make better use of a higher revving engine combo.

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. … Switching from a gear set of 3.55 or 3.73 to 4.10 gears will affect your gas mileage slightly as your engine will be turning more times to rotate the rear wheels once.

What gear ratio is best for fuel economy?

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. The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy.

Is 3.08 a good gear ratio?

Yes, you are exactly right, towing with a 6 speed with 3.08s is still better than towing with a 4 speed and 3.73s. If its a heavy trailer, you will probably never use 5th and 6th gears, but who cares? crank turns to rotate the rear wheels once that counts.
