## How do I choose a gear ratio?

The only way to accurately determine the gear ratio in the car is to remove the cover or pull the gears and count the teeth on both gears.

That is not easy, but at least with GM gears, the numbers are stamped on the side of the ring gear..

## Is 3.55 or 3.73 gears better?

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.

## What are 4.88 gears good for?

Pros and Cons. The pros are that these gears have a stronger V6 third member (in the rear) with lower gears that are suitable for larger tires, and (most importantly) they can be had for less than a full ring and pinion install. If you have an IFS truck, you can swap in the 4.88 IFS front diff.

## What’s the difference between 4.10 and 4.11 gears?

the difference between 4.10 and 4.11 is that 4.10s have 41 ring gear teeth and 10 pinion teeth. 4.11s have 37 ring gear teeth and 9 pinion teeth. same way that 45 ring gear teeth and 11 pinion teeth will give you 4.09s.

## How much does it cost to get 4.10 gears installed?

Installation costs will vary, but a good rule of thumb is between $250 and $300. Be sure to work with a reliable shop that you trust for installations. You can also save money on your installation labor by having your Trac-Lok rebuilt at the same time as your gears are installed, see drop down option above.

## WHAT WILL 4.10 gears do?

When accelerating from 50 to 70 mph, engine speed increases by about 800 rpm. Put 4.10:1 gears in the same car, and engine speed increases by 1060 rpm—the difference is 40 rpm per mph with the 3.08s versus 53 rpm per mph for the 4.10s. The greater rate of rpm increase versus road speed provides greater acceleration.

## What’s the best gear ratio for 35 inch tires?

Depending on the axle, the next lowest ratio from a 4.10:1 is most likely the 4.56:1, which should be selected for towing and performance. Because of the extra weight associated with off-road tires, we usually recommend going with a performance-minded gear ratio for any tire size above 35 inches.

## Are 3.73 or 4.10 gears better?

Vice versa, if the gear ratio is lower it has worse acceleration but a higher top speed. So, by changing your gear ratio, no power levels are being changed, just the torque….WHICH GEAR RATIO IS FOR YOU?3.73 RATIO4.10 RATIOBetter gas mileageWorse gas mileageHigher top speedLower top speed2 more rows•May 12, 2020

## Is a 4.10 gear ratio 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. … A 4.10 rear axle ratio is ideal for towing larger 5th Wheel or Gooseneck trailers.

## Is 3.42 or 3.73 better?

The 3.42 is fine for towing smaller boats, plus you will get better gas mileage for everyday driving. If I were towing frequently on hilly roads, I might would go for the 3.73 for better gas mileage while towing, but the 3.42 should be fine with a 205.

## What gear ratio is best for fuel economy?

The lower the number, the better fuel economy, and the higher the number the more towing power you have, but fuel economy suffers. For instance, a 3:31 gets better fuel economy than a 3:73. On the other hand, a 3:73 or perhaps a 4:10 will tow much more, while fuel economy greatly drops.

## Is 3.08 a good gear ratio?

Two common base axle ratios for trucks are 3.08 and 3.42. A 3.73 ratio is suitable for regular light towing. If you plan on towing a fifth-wheel trailer or anything heavier than 5,000 pounds, you should consider a 4.1 axle ratio. A 4.1 ratio allows a towing vehicle to start moving without as much throttle.

## Are 3.73 gears good for highway?

Well, if you plan on doing a lot of freeway driving, you don’t want to choose a gear that’s too low for your car because you’ll be going down the freeway at too high of an RPM. … Shorter gears (higher numbers) are much better suited for accelerating, such as 3.55, 3.73, 3.91’s, 4.11’s etc.

## What are 4.11 gears good for?

4.11:1 is a “lower” gear ratio, meaning you have more torque, lower top speed, and you will generally consume more fuel. Usually people put 4.11:1 gears in trucks to be used off-road for the extra torque and the better “crawling” capabilities.

## What does a 4 11 gear ratio mean?

The number refers to the pinion to ring gear ratio in the differential. … The 4:11 Gears will get you faster acceleration higher rpm at any given speed and increased fuel consumption. The 3:73 Gears will give you decent acceleration, lower rpm at any given speed and improved fuel consumption.

## Does higher gear ratio mean faster?

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.

## How fast can you go with 4.10 gears?

On the highway a 4.10 gear will only be about 200 rpms more at around 75 then a 3.73. And with the Automatic you will need all the help you can get. Top Speed of our GT’s should be between 145 and 155 depending on the tune of your chip if you have one.

## Which gear ratio is faster?

The higher the number the better the car will accelerate, but at the expense of high speed cruising. Now for the confusing part of the story. A high numerical gear ratio is called a low gear or low rear end, and vice versa. Low gears give fast acceleration, high gears give better cruising.
