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. This is known as the final drive, differential gear, Crown Wheel Pinion (CWP) or ring and pinion.

Are 3.73 or 4.10 gears better?
4.10s are going to accelerate faster and decelerate faster on lift. However the trade off is greater fuel consumption per mile driven and higher engine speed per given road speed. In basic terms the 4.10s will feel quicker and 3.73 will feel faster.
Does higher gear ratio mean more speed?
Gear ratios can be boiled down to a single statement: Higher ratios (with a lower numerical value) give better torque/acceleration and lower ratios allow for higher top speeds and better fuel economy. Higher ratios mean the engine has to run faster to achieve a given speed.
How fast can you go with 3.73 gears?
One of the more interesting details is how the 3.73 affects 0-60 mph acceleration. While 3.31 Mustangs do nearly 70 mph at the top of second gear, cars equipped with the 3.73 just squeak by, topping out at 61 mph.
What is a 3.73 gear ratio 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.
What are 3.55 gears good for?
3.55 gears will give you better gas mileage while 3.73 gears give you better acceleration and performance. The numbers you are using are common Final Drive Axle Ratios for vehicles, so the question will be answered in that context.
What gears are best for 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 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.
How does gear ratio 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.
How does gear ratio affect horsepower?
Changing gears, or changing gear ratios, changes the Torque output. (The lower the gear, the more torque you have available.) Horsepower is a function of both torque and speed. Increasing torque by shifting to a lower gear also means that the rotational speed is lower, thus horsepower does not increase.
What are 410 Gears good for?
This equates to a greater amount of power transferred to the wheels. Installing 4.10 gears improves the car's performance on the track but with negligible effects to the highway driving. If your car is equipped with an overdrive, you may not even notice a difference in gas mileage with the new higher gearing.
Is 3.31 or 3.55 axle ratio better?
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.
Is a 3.92 rear axle ratio good?
But opt for the higher 3.92 axle ratio and that same truck packs a higher towing capacity of 9,930 pounds. ... A higher axle ratio (like the 3.92 we mentioned earlier) will allow for higher towing capability, but it requires higher engine rpm for any given speed and then results in lower fuel economy.
Is 3.55 or 3.73 better?
PERFORMANCE: The larger the axle ratio number, the quicker the truck will accelerate. For example, a truck equipped with 3.55:1 axle gearing will accelerate faster than one equipped with a 3.31 axle ratio. Similarly, a pickup with a 3.73 axle ratio will be faster than one with 3.55s.
Can I tow with a 3.23 gear ratio?
3.23 is a perfectly fine towing gear.
Which rear end gear ratio is best for fuel economy?
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.
