Are 3.73 or 4.10 gears better?

4.10 gear ratio:

What's the rpm difference between 3.73 gears and 4.10 gears?

What it does, is this: 3.73, for every 373 rotations of the driveshaft you get 100 rotations of the axle, and for 4.10, for every 410 rotations of the driveshaft you get 100 rotations of the axle. Now, this means that your engine is spinning faster on 4.10 rather than 3.73.

Are 3.73 or 4.10 gears better for towing?

For towing, the 4.10 is better. For a heavier load, I would agree that the lower gearing is better. For a light load (4k lbs), 3.73's would do just fine. If you foresee towing heavier loads in the future (getting a larger TH, etc), then 4.10's would be the better choice.

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 4.10 gears good for highway?

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.

WHAT WILL 4.10 gears do?

Lower 4.10:1 gears would make the engine turn 4.10 times for each turn of the tire, so lower gears cause higher engine rpm at any road speed. If you continue to visualize the example of removing lug nuts with the long or short wrench, it will help you understand how to gear your car for quarter-mile acceleration.

What gear ratio is best for acceleration?

Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91's, 4.11's etc.

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.

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 a 3.73 rear end good for towing?

So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21. But it will also use more fuel in all situations because the engine's rpm will be higher.

How much can I tow with 3.73 gears?

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

Can I tow with 3.73 gears?

The 3.73 will be a good match for 8500 lbs. If you ever think you might go heavier if you have the option get the 4.10. It isn't that the 3.73 won't tow as much as the 4.10 it is that it will often have to do it in a lower gear and actually spin more rpm towing.

Which gear ratio is best for towing?

The higher the ratio, the more revolutions per minute. 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.

Is a higher or lower 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 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 are 4.11 gears good for?

If you go to a 4.11 you will increase your RPM at any given speed. Nice if you need more power at highway driving, climbing hills, restarting at stoplights etc.. 4.11's make your truck "feel" like you have more HP from stoplight to stoplight and pulling hills.

Is a 4.10 gear ratio good?

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 gears should I run with 35s?

If it's an automatic, you'll ideally want 4.56 gears. 4.10 isn't bad at all on the highway with 35s, but 4.56 is perfect. That's about perfect.

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.

What is the gas mileage difference between 3.73 and 4.10 gears?

Re: Mileage Difference between 3.73 and 4.10 rear end (OverRHeads) Real world difference between 3.73 and 4.10 gears is going to be about 4-5 mpg pulling a load.

What is the best gear ratio for 33 in tires?

4.56 works well for the 3-speed automatic and 33's, 4.88 is optimal for the 5-speed manual transmission. With the 4-speed automatic, 4.88 isn't even enough for 35's.

Are lower gears better for towing?

Towing Axles: For maximum power and towing capability you want an axle ratio that is higher in the number of drive shaft rotations for every tire rotation. The reason for this is the lower gear sets (higher value numerically) put more low speed torque, or towing power, at the rear wheels.

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.

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.

Does higher gear mean faster car?

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.
