How to Find Your Gear Ratio by VIN

The gear ratio of a vehicle may be determined in several different ways. It is possible to ascertain this essential knowledge by counting the number of teeth on the ring gear and the pinion gear.
You also have the option of looking up the gear ratio by entering the 17-digit vehicle identification number (VIN) of your vehicle.

Suppose you are interested in learning how to accomplish this. In that case, you can read an in-depth explanation of how to decode a VIN plate and determine the gear ratio that your vehicle utilizes in this article.

The gear ratio is stored in the VDS part of the vehicle identification number (VIN) of a vehicle. The Vehicle Identification Number (VIN) includes a feature called the vehicle documentation section (VDS). The VDS, which may be located anywhere from the fourth to the eighth character, provides information on the manufacturer, model, and gear ratio of a particular car. If the gear ratio is not included in the vehicle identification number (VIN), you must figure it out using other methods.

What Is a VIN Number?

Every single motor vehicle has a unique number known as a Vehicle Identification Number (VIN). The Vehicle Identification Number, or VIN, is comprised of 17 digits. If you are not acquainted with the technique, deciphering a VIN plate is a daunting undertaking.
You are in luck since there is a simple way to decode a vehicle identification number (VIN) plate. Once you do so, you will have access to a plethora of information about your vehicle.

Following is an explanation of the significance of each number that may be found on a VIN.

  • The first number of the VIN indicates the nation in which the automobile was produced.
  • In this particular instance, the manufacturer is indicated by the second digit in the serial number.
  • The classification of the automobile may be deduced from the first letter of the vehicle identification number (VIN).
  • The fourth through eighth characters provide particular information about the vehicle, including the manufacturer, model, series, transmission, and other features.
  • The very final digit is a unique security code exclusive to the company.
  • The tenth digit of the vehicle’s VIN indicates the year it was manufactured.
  • Your automobile was manufactured on the eleventh assembly line, represented by the corresponding character.
  • The remaining digits represent the unique production number for the one-of-a-kind automobile.

To interpret your Vehicle Identification Number (VIN), you may use one of several free online VIN checkers. You may also talk to a mechanic, who, armed with a VIN decoder, can offer you an exhaustive rundown of the information that is included in the identifying number of your car.

How Do I Find My VIN Number?

There will be a wide variety of possible VIN placements for automobiles. You are not looking in the right place if you cannot find a Vehicle Identification Number (VIN) plate on your vehicle since having one is mandated by law.

The vehicle identification number, or VIN, may often be found in one of the following locations:

  • Typically located on the front of the engine block, under the hood.
  • The dashboard is located on the passenger side. A typical position is the area where the dashboard meets the windshield.
  • Inside the door, most of the time on the driver’s side.
  • Regarding the documents that serve as the car’s title and registration.

When you have found the VIN sticker for your car, you can then begin the process of decoding it to find out the gear ratio that is appropriate for it.

What Does the Gear Ratio on Cars Mean?

Before we get into the specifics of determining your gear ratio using your vehicle identification number (VIN), let’s start by defining what a gear ratio is. To put it another way, the input gear is connected to a cog on the side of the gearbox that is next to the engine, and the output gear is connected to a cog on the side of the gearbox that is adjacent to the road wheels.

Each year, from 1 to 5, has a unique gear ratio and makes use of a cog that is a different size. As an example, the first gear is the one that is used while starting a motor vehicle. Therefore, the gear ratio has to be appropriate to carry out this job.

The input gear for the first gear is much more compact than the input gear for the fifth gear. When the size of the input gear is reduced compared to the outer cog, the gear ratio improves.

When the input gear spins the engine faster than the output gear rotates the wheel, the most torque is created. This is because the input gear turns the engine faster than the output gear. It takes a significant amount of torque to get a vehicle moving again once it has been stopped.

Because of the momentum of the vehicle, the amount of torque that is needed will decrease when the gears in your vehicle change. Because the input gear is more significant than the output gear, the fifth gear has a lower ratio than the previous gear.

To get a car’s gear ratio, the number of teeth on the input gear must be divided by the number of teeth on the output gear.

How to Find Gear Ratio by VIN

If you do not want to count the teeth on the various cogs in the gear system, there is an alternative method that is much easier that you can use to estimate the gear ratio of your automobile.

As was just said, the fourth through the eighth digits of the vehicle identification number (VIN) for your car include essential information. The term given to this group of characters is the VDS, which stands for the vehicle description section.

On the other hand, the gear ratio of a car won’t be included in the VDS from every manufacturer. If you want to be optimistic about whether or not your VIN consists of the gear ratio, you must employ a free online VIN checker or decoder.

Suppose the engine turns 3,73 times for every complete revolution of the wheel. In that case, the gear ratio of your vehicle will be 3:73:1. If the gear ratio is recorded in the vehicle identification number (VIN), then the value 3731 will be shown on the vehicle data screen (VDS).

In the Vehicle Dynamic Simulator (VDS), you will find characters who reflect the mod brand, series, and other aspects of the vehicle. If the gear ratio is included in the vehicle identification number, it will be included here.

Other Methods of Calculating Gear Ratio

If the gear ratio is only sometimes provided by the vehicle identification number (VIN) of a car, where else can you get it? Therefore, you must open the hood and work through the mathematical challenges.

The gear ratio of your vehicle may be determined by the following:

  • I am counting the revolutions of the rear wheel of a vehicle with rear-wheel drive (RWD) for each full rotation of the powertrain. For instance, if the wheel turns four and a half times, the gear ratio will be 4.50:1, which indicates that the percentage of gears will be 4:1.
  • Calculate the ratio of the total number of teeth on the input and output cogs to the total number of teeth on the cogs by dividing the two numbers.
  • Please review the owner’s manual for your vehicle.

How Important Is Gear Ratio?

Many drivers can go their whole driving career without ever knowing the gear ratio of their vehicle. By utilizing gear ratios, drivers may determine the fastest possible speed for each gear. In addition to this, when you are working on the car’s tires, you may find that the gear ratio has to be adjusted.

It is more common for drivers of muscle cars and trucks to alter the gear ratio of their vehicles, which is sometimes referred to as gearing. The gearing of a car can help the engine operate more effectively and permit faster speeds in various ratios.

Altering the gear ratio of a vehicle may have several additional benefits, including the following:

  • A reduction in fuel use.
  • The deterioration of certain sections was slowed down significantly.
  • Boosts the vehicle’s pulling capacity.
  • Acceleration and speed are both increased as a result.
  • Increases the amount of torque in a variety of gears.

You can offer your car the extra power it needs in all of the ratios by modifying the gear ratio. This will allow it to transport higher weights. Furthermore, since there is considerable torque creation, your vehicle will accelerate more swiftly.


It is easy to determine the gear ratio of a vehicle based on its VIN. The only thing that has to be done is to locate the component of the VIN known as the VDS, which may be found between the fourth and eighth letters. If you do not know how to decode a VIN, you may find out what each number in the VIN of your automobile represents by using an online VIN checker.

Suppose the gear ratio is not included in the vehicle identification number (VIN) of your vehicle. In that case, you may determine it by dividing the total number of teeth on the input gear by the total number of teeth on the output gear. Alternately, you may keep track of the number of times each wheel spins while the powertrain is turning.

You may discover more about the engine of your automobile now that you know how to find your gear ratio by using the VIN of the vehicle. To improve the performance of your car, you can experiment with changing the gear ratio.
