Quick Answer: What Gear Ratio Is Best For Speed?

Do bigger tires change gear ratio?

Taller than stock tires alter the final drive ratio of your 4×4 at the tires and effectively decrease the power you can put to the ground.

The bigger the tires are, the more noticeable the change.

The added weight and wind resistance also tax the engine..

Can gears increase torque?

The rotary machine’s output torque is increased by multiplying the torque by the gear ratio, less some efficiency losses. While in many applications gear reduction reduces speed and increases torque, in other applications gear reduction is used to increase speed and reduce torque.

Is a 3.42 gear ratio good?

Lower numeric axle ratios may help reduce how much an engine has to work while cruising at highway speeds, and can potentially help improve fuel economy. … For instance, the 3.42:1 ratio included on many Canyon V-6 and Sierra 1500 models offers a good all-around blend.

How do gear ratios affect speed?

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.

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.

Is 3.55 or 3.73 gears better?

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.

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 is the best gear ratio for drag racing?

With a 3.08:1 rear gear, the effective First gear ratio is equal to a 2.20:1 First gear Muncie four-speed with 4.56:1 rear gear. In the quarter-mile, Fourth gear is equivalent to running a 3.79:1 rear gear. But shift into 1:1 Fifth gear and enjoy the highway cruising rpm of a 3.08:1 rear gear.

Are 4.11 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.

Is a 4.10 gear ratio good?

FACT: A 4.10 axle ratio is ideal for towing heavy loads in a mix of city and highway driving and when towing on varied or steep grades. A 4.10 axle ratio will provide improved acceleration in stop and go city traffic.

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.

Does more gears mean more speed?

Having more gears allows smaller, more economical engines to power larger vehicles or improves the efficiency of existing engines. … The new seventh gear is taller, lowering engine rpm at any given speed, thereby decreasing fuel consumption and CO2 output without compromising acceleration or top speed.”

Which gear ratio is faster?

The higher the number the better the car will accelerate, but at the expense of high speed cruising. Now for the confusing part of the story. A high numerical gear ratio is called a low gear or low rear end, and vice versa. Low gears give fast acceleration, high gears give better cruising.

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

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.

How much can a 5.3 L v8 tow?

Its towing capacity is 7,900 pounds. 5.3L V8 Engine: With this available engine, the Chevy Silverado 1500 achieves 355 hp and 383 lb-ft of torque. Towing capacity is elevated to 11,600 pounds. 6.2L V8 Engine: Equipped with this engine, the Chevy Silverado 1500 can tow its maximum of 13,400 pounds (on the RST trim).

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.

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.

Is 3.73 a good gear ratio?

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.

What are 4/10 gears good for?

4:10 gears give you better acceleration and speed at fifth gear. If installed properly, you won’t get a whine easily. And who doesn’t love a whine-free driving. When you want a luxury ride with all the smoothness, 4.10 gears are pretty useful in that criteria.
