Quick Answer: What Are 3.08 Gears Good For?

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..

What gear ratio is best for speed?

If you prefer top speed to dragstrip performance, then higher axle gears, like 2.76:1 or 3.08:1, may be called for. The higher gears will reduce engine rpm versus road speed. Another way to look at it is that the car will go faster at the engine’s rpm limit than it would with lower gears.

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.

Do 3.73 gears make a difference?

The 3.73’s don’t go quite that far — but they’re with 10% of that change. So it will be a VERY noticeable difference. Highway fuel mileage will take a bit of a hit; city mileage has the potential to improve with the 3.73’s. All this assumes your rear tire height stays the same.

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.

How fast can you go with 4.10 gears?

With 4.10s…. With stock size tires you can go 150 mph at 5393 rpm in 5th gear.

Are 3.73 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.

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 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.

Does gear ratio affect horsepower?

Motor HP does not change when you change gear ratios. The only thing that changes is torque. A dynamometer measures torque and RPM, and from those two values calculates horsepower. When you change gear ratios both RPM and torque will change but horsepower will not.

Does higher gear ratio mean faster?

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 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. Not that you are looking for a higher top end speed.

Are 3.73 or 4.10 gears better?

Is a 3.08 gear good for towing?

Two common base axle ratios for trucks are 3.08 and 3.42. A 3.73 ratio is suitable for regular light towing. … If you’re driving a diesel truck, you don’t need an axle ratio numerically higher than 3.7 to pull heavy trailers, as diesel engines already have very high torque.

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.

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 37 inch tires?

Increasing the 4.10 axle ratio by 16 percent would dictate the need of a 4.75 axle ratio to match the 37-inch tires. The exact axle ratio you need probably won’t be available, so it’s okay to round up when selecting the right ring and pinion. In this case, a 4.88 axle ratio would be acceptable.

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.

What are 3.73 gears good for?

A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.
