What is the gear ratio of a Chevy Trailblazer?
The gear ratio of a vehicle is a crucial aspect that affects its performance, fuel efficiency, and overall driving experience. For Chevy Trailblazer owners or potential buyers, understanding the gear ratio can provide insights into how the vehicle will perform under various conditions. In this article, we will explore what gear ratios are, the specific ratios for different Chevy Trailblazer models, and why they matter.
What is Gear Ratio?
Gear ratio refers to the ratio of the number of teeth on two gears that are meshed together. In automotive terms, it typically describes the relationship between the engine's output and the wheels' rotation. A higher gear ratio means more torque and power at lower speeds, while a lower gear ratio allows for higher speeds but less torque.

Frequently Asked Questions
How do I figure out my gear ratio?
The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a “[result] to 1” ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1.
How do I tell what gear ratio I have on my Chevy?
Re: Find your differential gear ratio
You can also turn the wheels and count how far the pinion turns to get a rough idea. 3.5 turns would be a 3.42:1 but 3.75 turns would be a 3.73:1 and so on... That RPO code sticker is great for finding out a lot of things about your van.
What is a 3.73 gear ratio good for?
For a truck, it is great for heavier loads where factory gear ratios that are 3.55 or 3.31. In a sports car, 3.73 gears will offer better acceleration while retaining top speed when compared to 3.55 gears that come factory on many sports cars.
What is the normal gear ratio?
The most common gear ratios used in cars are 1st gear: 3.5-4.5, 2nd gear: 2.0-2.5, 3rd gear: 1.5-1.8, 4th gear: 1.0-1.3, 5th gear: 0.8-1.0.
What gear ratio is my transmission?
Here's the formula for calculating gear ratio: (RPM x Tire Diameter Inches) / (Final Drive Ratio x Transmission Gear Ratio x 336) = Actual numerical gear ratio to the ground from every revolution of the engine.
How to find gear ratio by VIN?
You don't. That information is not contained in the VIN, UNLESS a specific model only gets one rear end ratio. VIN tells country of manufacture, vehicle make, class, engine type, size, date of manufacture, plant and serial number. That is the ONLY information contained by the VIN.
