What's the difference between 4.10 and 3.73 gears?

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's the difference between 3.73 and 4.10 gear ratio?

For example, if the ring gear has 37 teeth and the pinion gear has 9 teeth, the ratio is 4.11:1. So for every turn of the ring gear, the pinion will turn 4.11 times. Additionally, with a gear ratio of 3.73, the pinion will turn 3.73 times for one turn of the ring gears, and for a 4.10, the pinion will turn 4.10 times.

Do 4.10 gears make a difference?

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.

Whats better 373 gears or 410?

4.10 is the typical gear ratio for a high-performance vehicle like a sports car or SUV because it provides better acceleration than 3.73 because of the faster second and third gears, which provide more torque at lower speeds to accelerate from a stop.

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.

3.73 Vs 4.10 Gears Cruising Speed Difference (Surprising)

Are 4.10 gears good for towing?

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 does a 410 rear end mean?

Gear Ratio: the ratio of the ring and pinion gears in the rear axle. So, if you have a 4.10:1 (sometimes 4.10) rear axle, the pinion will turn 4.10 times for every single turn of the ring gear or in other words, for every 4.10 turns of the driveshaft, the rear wheel will spin once.

What gear ratio is best 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 is a good gear ratio for a street car?

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.

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!

Is higher gear ratio better?

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.

What gears are better for towing?

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 is a good rear end gear ratio?

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.

Which gear ratio is better for gas mileage?

Best MPG ratio

If getting the best fuel economy is priority, then choose the lowest numerical number offered, such as 3.08, 3.23 or 3.31. This applies to highway driving; city driving mpg isn't really affected by the axle ratio. If you do a mix of both, go with the “standard” axle ratio offered by the manufacturer.

Is a 3.73 axle ratio good for towing?

If you are going to be taking your truck on long trips or using it as your daily driver for hauling groceries, this is a good place to start. For the Best Towing Capacity: If you are planning on towing large payloads and have a V8 gas or diesel engine, an axle ratio between 3.55 and 3.73 will be perfect.

Does changing gear ratio affect torque?

The primary purpose of the gear ratio is to reduce the torque by increasing the speed, and vice versa. Your car won't move at higher gear ratios because, at the initial stage, you need more torque than power.

What rear gear ratio is Nascar?

NASCAR gives the teams two or three choices for rear‐end gears at each track. At Watkins Glen, for example, one choice is a “422 gear”, which is a 4.22:1 gear ratio. The input to the rear‐end gear makes 4.22 rotations for every 1 rotation the larger gear makes.

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.

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.

How do I choose a 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.

Does a bigger sprocket make you go faster?

A bigger rear sprocket/ smaller front sprocket will give you an increase in acceleration but decrease your top speed. A smaller rear sprocket/bigger front sprocket will reduce you acceleration but increase the top speed.

Why do lower gears have more power?

Within the capability limits of the engine, shifting into a lower gear allows the engine to turn faster, allowing it to produce more power which the transmission converts into greater output torque for a given wheel speed.

What is the best rear end for drag racing?

Ford 9"- The Ford 9" is definitely the most popular of the rear ends in drag racing. It offers good strength characteristics and the largest variety of gear choices. The thirdmember type center section allows a racer to have multiple gear ratios available and is much easier to change than a rear loading type rear end.

How much can I tow with 3.73 gears?

Administrator. Correct, 3.73 and 4.10 gears will tow up to 3500.
