What are 3.73 gears good for?

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.

Are 3.73 or 4.10 gears better?

4.10 gear ratio:

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.

Are 3.73 gears any good?

IMO, 3.73s are really the best all around gears in a GM truck. I've had both in both full size and mid size trucks/SUVs and I hated the 3.42 in both. The difference in fuel economy is invisible really. I think the 3.73s just do a better job of keeping the engine in the best RPM range, especially when towing.

Is 3.55 or 3.73 gears better?

End of dialog window. 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.

Can 3.73 gears handle 35s?

You can do it but it's definitely not ideal. The ratios with a 5.13 first on a 3.73 rear end and 35's (your proposed setup) is very slightly taller than what a stock 6MT Tacoma is in first gear so it's not like you're going to be causing massive wear getting started.

Can I run 37s with 3.73 gears?

37s on 3.73s will do more damage than good. You'll definitely need to regear to 4.88s or 5.13s. You'll also want to have a front D44 or beef up the D30 if that's what you have.

How much does Regearing cost?

If you are looking to regear and can find an affordable shop, you could complete the whole project for around $1,500 or less. What is this? To break down the costs, you can expect a gear overhaul kit to cost anywhere from $600 to $1,200.

What does a 3.73 gear ratio mean?

This number is shown in the ratio, which represents the number of the ring gear's teeth divided by the number of the pinion's teeth. If a truck has an axle ratio of 3:73:1, for example, the driveshaft turns 3.73 times for each full wheel spin.

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.

Can I run 33s on 3.73 gears?

With 3:73 gears and 33" tires you are fine.

What are 3.55 gears good for?

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.

How can you tell if you have 3.73 gears?

Rotate the marked tire one revolution while counting how many times the driveshaft rotates. eg, If your driveshaft made 3 3/4 revolutions, that would determine a 3.73 gear ratio. If you get approximately 2 3/4 revolutions, you have a 2.76 gear ratio.

What is the difference between 3.42 and 3.73 gears?

In short, the core differences are the 3.73 gear ratio gives you a lot more acceleration and torque, the 3.43 has a higher cruising speed and better fuel economy. The question of which one is the better option can best be answered by the specific application intended for your vehicle.

What gear ratio is the fastest?

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'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 are 411 gears good for?

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).

What are 4/10 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.

Do front and rear gears have to match?

Yes they must match. Picture your rear axle doing 50 and your front doing 40 or 60. Your transfer case will not last long.

How much does it cost to change the gear ratio in a truck?

As to cost, depending on where it is done, it could cost you as little as 750 dollars to as much as 1500 dollars per axle. Best prices would probably be a performance shop that does it all the time.

Which is better close ratio or wide ratio transmission?

The best transmission ratio depends on how much track time you'll see and the ratio of your rear axle gear. With a street-friendly gear like a 3.73:1 or lower, go with the close-ratio transmission. If you've got a steeper gear and you're less concerned about drivability, choose the wide-ratio.

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.

Will bigger tires affect 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 does Regearing a truck do?

Re-gearing can and will improve your vehicles top speed, fuel efficiency and performance. Off-roading and upgrading to larger tires changes to overall diameter of the tire, roll resistance, tire rotation and adds weight of the tires into the mix.
