The rear axle ratio of your car is an important factor to consider when it comes to performance and fuel economy. A 3.92 rear axle ratio can make your car more fuel efficient and provide a smoother ride, but it’s important to make sure your car actually has a 3.92 rear axle ratio before you make any modifications. In this article, we’ll discuss what a 3.92 rear axle ratio is and how you can tell if your car has one.
What Is a 3.92 Rear Axle Ratio?
The axle ratio of a car is the ratio of the number of rotations of the driveshaft to the number of rotations of the rear axle. A 3.92 rear axle ratio means that the driveshaft will rotate 3.92 times for every one rotation of the rear axle. This ratio can affect the performance and fuel economy of your car, as a higher ratio will give you more power and torque, while a lower ratio will provide better fuel economy.
How to Tell If Your Car Has a 3.92 Rear Axle Ratio
There are a few ways to tell if your car has a 3.92 rear axle ratio. The easiest way is to look at the identification tag on the rear axle. The tag should show the ratio of the rear axle, and if it is 3.92, then your car has a 3.92 rear axle ratio. If the tag is missing or illegible, you can also measure the circumference of the driveshaft and the rear axle and divide the circumference of the driveshaft by the circumference of the rear axle. If the result is 3.92, then your car has a 3.92 rear axle ratio.
Benefits of a 3.92 Rear Axle Ratio
A 3.92 rear axle ratio provides several benefits over lower ratios. A 3.92 rear axle ratio will give your car more torque and power, which can be helpful if you drive on hilly roads or often tow heavy loads.
