What does 4.88 gear ratio mean?

Short (low) gears have HIGHER numerical numbers, such as 4.11, 4.30, 4.56, 4.88, 5.13, 5.36, etc. In simple terms, the numbers mean how many turns of the drive shaft to one turn of the rear wheel.

What is the best gear ratio for speed?

In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears. Lower gears are required if the car is very heavy, or if the engine makes its power at the upper end of the rpm scale.

What gear ratio is best for 40 inch tires?

For those huge 40 inch tires, 4.56 gears would be much better than 4.10. Actually, if you want to keep the RPM vs speed the same as the factory setting with those 40 inch tires, you would need something like a 4.90 gear ratio.

Which rear end gear ratio is best?

The most popular rear-end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy. This is a good ratio for the occasional towing or hauling individual. For a person who tows more often, and heavier loads, the 3:73 or 4:10 may be more appropriate.

Is a 3.31 axle ratio good for towing?

Normally, the 3.31 would get you better gas mileage, on highway. But, with the 3.55 you will get a bit more pulling power so less time at higher RPM to get your trailer moving and when going uphill. If most of your towing is flat highway, the 3.31 should do you fine.

Does gear ratio affect horsepower?

A higher numeric axle ratio (4.11:1) keeps the engine running in the higher horsepower range, thus improving performance.

What's the best gear ratio for drag racing?

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.

What is a 3.31 electronic locking axle ratio?

Consider that with a 3.31 axle ratio, the driveshaft turns 3 1/3rd times for every revolution of the rear wheel. With a 4.30 ratio, it turns 4 1/3rd times for every revolution of the rear wheel. The numerically higher gear ratio (in this case, 4.30) increases wheel torque and improves acceleration from low speeds.

What is a low gear ratio?

Low Ratio. Low ratio gears are gears where the pinion gear (attached to the motor) has fewer teeth than the ring gear (the gear it turns). So if the pinion gear has 10 teeth and the ring gear has 30 teeth, the ratio is 1:3.

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.

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. You do not want go too low in an effort to increase power to the wheels and/or relieve stress in the rest of the drivetrain.

What gear ratio should I use for 35 inch tires?

That's why I run a 4.56 gear ratio with 35″ tires. This gives me decent fuel efficiency at highway speeds, and enough low end power to throttle through difficult obstacles.

What gears for what speed?

Remember each car will be geared slightly differently, but a good rule of thumb for changing gears is that first gear is for speeds up to 10 mph, second gear is for speeds up to 15 mph, third gear is for speeds up to 35 mph, fourth gear is for speeds up to 55 mph, fifth gear is for speeds up to 65 mph, and sixth gear ...

Which gear is the fastest in a bicycle?

High Gear = Hard = Good for Descending: The “highest” gear on your bike is the largest chain ring in the front and the smallest cog on your cassette (rear gears). In this position, the pedaling will be the hardest and you'll be able to accelerate while traveling downhill.

How 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.

What is EDLS axle?

What does the Electronic Limited-Slip Differential (eLSD) do on my Ford? The available Electronic Limited-slip Differential system directs torque, enabling the vehicle to drive over terrain and road conditions that a conventional axle cannot. The system is active at all times and requires no driver interaction.

What is a 3.55 axle ratio?

Understanding Axle Ratios

Technically, the number should be expressed as a ratio, such as 3.55:1, meaning the drive shaft turns 3.55 times for each turn of a wheel. But that gear ratio would most commonly be referred to as "3.55" or simply "three fifty-five."

What does non-limited slip axle ratio mean?

Non-Limited Slip

Standard differential wheels are designed to send power to one wheel at a time. Therefore, when one wheel loses traction, the standard differential has a tendency to revert the majority of the power to the wheel that is under the least resistance.

What gears are good for street racing?

If we have a daily driver, 2.55 to 3.25 gear ratios typically work best, whereas a street/strip application we would usually use a 3.42 to a 3.90 gear ratio, and race applications most commonly use a 4.10 and above gear ratios.

What gear ratio is a 2 speed Powerglide?

What Is The Gear Ratio Of A 2 Speed Powerglide? OEM powerglides are made with 2 gears: 1 at each input.

What gear ratio do I need for 1/8 mile?

4.56 with 32" tires could be a good ratio for 1/8 mile considering your RPM limit.

What makes a car accelerate faster?

In terms of acceleration, torque plays a bigger role in how quickly your car accelerates. That's because the torque is a result of the force the pistons generate and at what speed. The quickest vehicles can generate high levels of this torque force at relatively low rpm. This allows the vehicle to accelerate quickly.

Is it better to have more torque or horsepower?

Basically, the faster the crankshaft spins with the same amount of force, the more power an engine will make. A car with more hp than torque will always be quicker since this gives a car acceleration and speed.

What is the cheapest way to increase horsepower?

5 Ways to Boost Horsepower for Under $500
