Is 3.55 or 3.73 gears 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.
What is a 3.55 axle ratio good for?
Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.
Are 3.73 gears good?
Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.
What gears are best for 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.
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 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 3.31 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.
What gear ratio is best for 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 a 3.73 rear axle ratio?
The number is expressed in a ratio, which represents the number of teeth on the ring gear divided by the number of teeth on the pinion. For example, a truck with a 3.73:1 gear ratio means that the driveshaft will turn 3.73 times for each complete wheel spin.
What is a 3.55 gear ratio?
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.”
How many teeth does a 3.73 ring gear have?
3.73 gears have 11 pinion gear teeth & 41 ring gear 41/11= 3.727 to 1. Factory ratio was 3.70.
Are 3.73 gears good for 35 tires?
You will be fine. Just gonna lose mpg and slow your truck down. I have run 35s with 3.73s and no issues at all. In fact, my recent Plat had a 4-inch lift, heavy 34.5 inch Nitto Trails, and 3.55 gears, and ran great!
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.
What is a good gear ratio for a muscle 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.
What gear ratio is better for torque?
The numerically higher gear ratio (in this case, 4.30) increases wheel torque and improves acceleration from low speeds. But the engine does have to run faster to achieve a given speed.
