Does a higher gear ratio mean more torque?
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.
What is true regarding a gear ratio of 4 1?
There is a trade-off between speed and torque, which is rotational power. When the gear ratio is 1:1, the amount of torque is the same, and the speed is the same. If you reversed the ratio (say, 4:1), you would cut the speed but boost the torque.
Does a lower gear ratio increase torque?
In general, a lower final drive ratio will lead to less torque at the wheels but a higher top speed. Meanwhile, a higher ratio will result in the opposite, i.e. more torque at the wheels but a lower top speed.
Is a higher gear ratio 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.
Are 3.73 or 4.10 gears better?
A 3.73 is a higher gear ratio for half ton pickups its not the best gear for pulling trailers, now the 4.10 gears come stock from the factory on newer trucks and is one of the best rear end gears to use if you plan on pulling a trailer. These both vary by fuel mileage consumption so choose wisely.
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%.
Are 3.73 gears good for highway?
Rear end gears (2.79’s, 3.00’s, 3.25’s, etc) are great for freeway driving, bit not good for 0-60 MPH or accelerating from a dead stop. 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”.
What rear axle 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 3.73 gears good for towing?
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.
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?
4.10:1
What gear ratio is better for towing?
A 3.73 ratio is suitable for regular light towing. If you plan on towing a fifth-wheel trailer or anything heavier than 5,000 pounds, you should consider a 4.1 axle ratio. A 4.1 ratio allows a towing vehicle to start moving without as much throttle.
Can you change the gear ratio on a truck?
You can change the axle ratio, and you can do it rather easily. Quite a few members here have gone from one ratio to the next. People with 3.21 and 3.55s are going up to 3.92 and even sometimes 4.10. A lot of the 4×4 trucks you see here with lifts and larger tires have gone with 4.10 or 4.56.
What gear ratio do I need for 35 inch tires?

| 3.31 | 5.71 | |
|---|---|---|
| 34″ | 2126 | 3668 |
| 35″ | 2065 | 3563 |

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.”
Is 3.55 a good gear ratio?
For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio. BEST TOWING RATIO: In general, the best towing axle ratio for most of the post-2010 pickups is in 3.55 or 3.73. Those ratios provide very good acceleration with gas V-8s and diesels.
How much does it cost to change the gear ratio in a truck?
As to cost, depending on where it is done, it could cost you as little as 750 dollars to as much as 1500 dollars per axle. Best prices would probably be a performance shop that does it all the time.
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 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 do I choose gear ratio?
The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.
Can you change gear ratio?
Luckily, some tuners, such as Sharkwerks, can alter the transmission’s gear ratios to improve acceleration and shifting frequency. There’s also the axle ratio to consider. As with the transmission, changing the axle ratio changes vehicle performance. A higher ratio means better acceleration, but worse efficiency.
Does gear ratio 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. The reseaon you dyno in 4th gear is becouse its a 1-1 ratio.
Does bigger tires change gear ratio?
If the Tires Are Bigger, the Gears Should Be Lower. Going to lower gears (ironically, a numerically bigger ratio) will increase the rpms of an engine (taking for granted the same diameter tire and going the same speed).
Can gear ratio be less than 1?
Typically, gears 5 and sometimes even 4 have ratios less than 1, which means that engine RPM will be less than wheel RPM in those gears. For example, gear ratio for 5th gear can typically be 0.9. Such gears (with gear ratios of less than 1) are called overdrive gears.
What is a 5 to 1 gear ratio?
For example, if a motor drives a 12T gear to a driven 60T gear on an arm, the 12T driving gear has to rotate 5 times to rotate the 60T driven gear once. This is known as a 5:1 ratio. The torque output is 5 times as much, however, the speed output is only 1/5.
Does gear ratio affect torque?
Gear reduction has the opposite effect on torque. The rotary machine’s output torque is increased by multiplying the torque by the gear ratio, less some efficiency losses. For example, if an electric motor drives a 13-tooth pinion gear that meshes with a 65-tooth gear, a reduction of 5:1 is achieved (65 / 13 = 5).
What is a good gearing ratio?
A gearing ratio higher than 50% is typically considered highly levered or geared. A gearing ratio lower than 25% is typically considered low-risk by both investors and lenders. A gearing ratio between 25% and 50% is typically considered optimal or normal for well-established companies.
What is highly geared?
high debts
What is ideal profitability ratio?
Profitability ratios assess a company’s ability to earn profits from its sales or operations, balance sheet assets, or shareholders’ equity. Profitability ratios indicate how efficiently a company generates profit and value for shareholders.
What is a good interest cover ratio?
Optimal Interest Coverage Ratio Generally, an interest coverage ratio of at least two (2) is considered the minimum acceptable amount for a company that has solid, consistent revenues. Analysts prefer to see a coverage ratio of three (3) or better.
