Question: What Are Transmission Gear Ratios?

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.

How do you read transmission gear ratios?

The ratio is the number of teeth on the driven gear (ring) divided by the number of teeth on the drive gear (pinion). So, if the ring gear has 37 teeth and the pinion has 9 teeth, the ratio is 4.11:1. That also means that for every one turn of the ring gear, the pinion will turn 4.11 times.

Are 3.73 or 4.10 gears better?

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. WHICH GEAR RATIO IS FOR YOU?

3.73 RATIO 4.10 RATIO
Lower torque Higher torque
Better gas mileage Worse gas mileage
Higher top speed Lower top speed

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.

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.

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 does a gear ratio of 4/9 mean?

Answer: this is it. Explanation: For every 9 turns of the driver the follower will make 4 complete rotations!

What is double clutching mean?

In simple terms, double clutching is the act of using the clutch pedal twice during a single shift between gears. Starting in motion in fifth gear, it goes like this: Clutch in, shifter out of fifth into neutral, clutch out, quick hit of gas pedal, clutch in, shifter out of neutral into fourth.

What does a 4 11 gear ratio mean?

4.11 is a gear ratio.. basically it means that the the pinion or driveshaft will turn 4.11 times for each rotation of the tires. The higher the ratio, the more times the the the engine, transmission, transfer case, etc turns to make the wheels spin which yields less top speed but more low end torque (usually).

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.

How fast can you go with 4.10 gears?

With 4.10 s. With stock size tires you can go 150 mph at 5393 rpm in 5th gear. Check out the rpm calculator in the tech section.

What are 4.11 gears good for?

The 4.11 gears are the ones you’d use in a more powerful car for drag racing to help it grip and not spin, meaning the gears are longer.

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.”

Will VIN number tell me gear ratio?

For most vehicles, the VIN does not provide gear ratio or limited slip information.

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.
