What gear ratio is best for 33 inch tires?

While 4.56 is ideal for 33" tires and 5-speed transmission, the 3-speed auto's lack of an verdrive makes 4.10 the best all-around street and offroad ratio.

Are 3.73 gears good for 33 tires?

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

What gear ratio is better for bigger tires?

But the easiest way to figure out the right ratio is to lower it the same percentage you increased the tire diameter over stock. For example, imagine your 4×4 came from the factory with 32-inch tires and 4.10 axle gears. Upgrading to 37-inch tires would calculate to about a 16 percent increase in tire diameter.

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.

Should I get 3.73 or 4.10 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. Do you plan on towing or moderate to aggressive off-roading?

Find Your Effective Gear Ratio With This Equation

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!

How fast can you go with 4.56 gears?

Registered. your max highway speed will be about 138mph @ 5000rpms with 4.56s & 33s.

Is a 4.10 gear ratio good for 35 inch tires?

4.10 will be just fine for 35's and Especially if you get a 4:1 transfer case for off road adventures. I recently went from 3.21 to 4.10 with 35" Terra Grapplers. It made a huge difference on my 2dr with manual transmission, It's just about perfect around town. I run at about 2400rpm at 70 in 6th gear now.

How do I choose the right gear ratio?

To find the ideal selection, multiply the final drive ratio by the redline speed in fourth gear (152 mph) and divide that by the top track speed (140 mph). This would yield a theoretical 3.33—which is close enough to the nearest available final drive ratio of 3.36:1.

Do bigger wheels affect gear ratio?

When taller tires are installed on a truck but the axle ratios stay the same; the effective gear ratio is reduced. This means the engine is forced to operate below its power band, and performance and fuel economy suffer as a result.

Does wheel size affect gear ratio?

A larger wheel would increase top end speed, a smaller wheel decreasing it. Gear ratios are gear ratios. For a given chainring tooth count moving at a given cadence, the smaller the gear in the rear the faster the wheel will turn. The larger the gear in the rear, the slower.

What is considered a low gear ratio?

A gearing ratio lower than 25% is typically considered low-risk by both investors and lenders. A gearing ratio between 25% and 50% is typically considered optimal or normal for well-established companies.

What gears for Jeep TJ with 33 tires?

While 4.56 is ideal for 33" tires and 5-speed transmission, the 3-speed auto's lack of an Overdrive makes 4.10 the best all-around street and offroad ratio for your TJ.

Do gears make car faster?

The simple answer is yes. More aggressive gearing creates a quicker car but not a faster car. A gearing change will have a noticeable affect on your car. If you swap in taller rear gears, you can gain some top-end speed, making your car faster, but you're going to be a bit slower leaving from a stop.

What is a good crawl ratio?

An ideal crawl ratio for general-use 4x4s is typically in the 50:1 range. Those who tackle more difficult terrain will strive to obtain at least a 100:1 ratio.

Will bigger tires affect my transmission?

Essentially when you increase your tire and/or rim size you are changing the ratio of all the components involved in making your vehicle stop and go. This includes the drivetrain, transmission, brake system, and all the associated parts within those systems.

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.

Can a Dana 35 Handle 35 inch tires?

Your friend's front axle is a dana 30, not a dana 35. And the front axle never sees more than about 50 percent of the stress that the rear axle does. 35" tires are not recommended on a dana 35.

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 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.

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.

What gear ratio is the fastest?

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 are 3.55 gears good for?

BEST TOWING RATIO: In general, the best towing axle ratio for most of the post-2010 pickups is in 3.55 or 3.73. Those ratios provide very good acceleration with gas V-8s and diesels.
