Question: Are 3.73 Gears Good For Highway?

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..

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.

Can I Regear my Jeep myself?

The only way you could do it yourself is if you have someone helping you that’s done at least 2 or 3 regears before.

WHAT WILL 3.73 gears do?

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. … Four-wheel-drive trucks will have a ratio in the front axle’s differential that closely matches that of the rear axle.

Is 3.42 or 3.73 better?

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 3.55 gears good for highway?

Well, if you plan on doing a lot of freeway driving, you don’t want to choose a gear that’s too low for your car because you’ll be going down the freeway at too high of an RPM. … Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc.

Is 3.23 a good gear ratio?

The engineers likely chose the numerically low gear ratio for fuel economy reasons. … A later swap to a four-speed and 3.23 rear gears woke up the performance of the car considerably. Yes, highway rpm increased as well, but I rationalized it by deciding that 3.23 gears provided a good balance of performance and economy.

What is a good gear ratio for a street car?

If it’s a daily driver, chances are you’ll want to keep your gear ratio at 3.23 or below for optimal performance and lower cruising RPMs. For street and strip applications, a popular choice ranges between 3.42s and 3.90s, giving you that extra oomph on the track while maintaining a tolerable cruising RPM on the street.

How much does it cost to get 4.10 gears installed?

Installation costs will vary, but a good rule of thumb is between $250 and $300. Be sure to work with a reliable shop that you trust for installations. You can also save money on your installation labor by having your Trac-Lok rebuilt at the same time as your gears are installed, see drop down option above.

Are 3.73 or 4.10 gears better?

Well-Known Member. 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 3.55 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 gear ratio is best for speed?

A gear with a lower numerical ratio, like 3.08:1, does not multiply torque as much, but with an equal rpm input will produce a higher axle or tire speed, all else being equal. This means that rear gear ratios are a compromise.

What’s the best gear ratio for 35 inch 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.

Are 411 Gears good?

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.

Does 3.73 gears make a difference?

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.

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 is the difference between 3.73 and 4.10 gear ratio?

Use this rule of thumb: The higher the gear ratio, the easier it is to get the vehicle moving and better accelerating, but lowers top speed. Vice versa, if the gear ratio is lower it has worse acceleration but a higher top speed….WHICH GEAR RATIO IS FOR YOU?3.73 RATIO4.10 RATIOHigher top speedLower top speed3 more rows•May 12, 2020

Does gearing affect horsepower?

It doesn’t affect horsepower or tourqe at all. Gears make your rear tires turn faster or slower. It also effects your top end speed and milage.

Do bigger tires change gear ratio?

When changing gears for taller tires, you are heading to a numerically higher gear ratio. The higher the gear ratio, the smaller the pinion gear.

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.
