Whatever your reason may be, finding your vehicle's gear ratio is essential. The gear ratio is the relation between the number of teeth on the ring gear and pinion gear in the differential. This determines your car's acceleration and top speed. In this article, we'll teach you how to find your vehicle's gear ratio by VIN, so keep reading!
What is a VIN?
A Vehicle Identification Number or VIN is a unique 17-digit code that serves as your car's fingerprint. It contains information about the make, model, year, and country of origin. It also includes the manufacturer, production number, and vehicle attributes such as engine type, body style, and transmission. The VIN is usually located on the dashboard, driver's side door jamb, or engine block. You can also find it on your vehicle registration and insurance documents.
Why is Gear Ratio Important?
Your car's gear ratio can affect its performance, fuel efficiency, and towing capacity. A higher gear ratio means more torque and lower top speed, while a lower gear ratio means less torque and higher top speed. Gear ratio also affects your car's ability to climb hills, accelerate, and maintain speed. By knowing your gear ratio, you can select the right gear for your driving needs and make informed decisions about modifications or upgrades.
Steps to Find Gear Ratio by VIN
Step 1: Identify the VIN
The first step is to locate your vehicle's VIN. As mentioned earlier, it can be found on your dashboard, driver's side door jamb, or engine block. Write down the 17-digit code and make sure it's accurate and complete.
Step 2: Decode the VIN
The second step is to decode the VIN to extract the relevant information. You can use online VIN decoders or consult your vehicle's manual to decipher the code. Look for the digits that represent the axle ratio or gear ratio. It's usually the last few digits of the VIN, but it may vary depending on the manufacturer.
Step 3: Check the Manufacturer's Website

Tips and Tricks
Here are some tips and tricks to make the gear ratio finding process easier:
Tip 1: Use a Magnet
If you can't locate the VIN on your engine block, use a magnet to find it. The VIN is usually stamped on a metal plate that's attached to the engine block. The magnet will help you locate the plate faster.
Tip 2: Check the Differential Cover
If you're still unsure about your gear ratio, check the differential cover. It usually has a tag or a stamp that indicates the gear ratio. You may need to remove the cover to see it, so make sure you have the proper tools and knowledge before attempting this.
