What are 3.73 gears good for? If you’re a car enthusiast, you’ve likely heard this question before. Simply put, 3.73 gears are a popular upgrade for many truck and muscle car owners who want to improve their acceleration and overall performance. In this article, we’ll dive into the details of what 3.73 gears are, why they’re popular, and what benefits and drawbacks they may offer.
What are 3.73 gears?
First, let’s define what 3.73 gears are. The term “gears” refers to the gears in the differential of a vehicle, which transmit power from the driveshaft to the wheels. Gears come in different ratios, which determine the amount of torque that’s sent to the wheels.
The ratio is expressed as a number: the number of teeth on the pinion gear, divided by the number of teeth on the ring gear. So, for example, 3.73 gears mean there are 3.73 teeth on the ring gear for every one tooth on the pinion gear.
Why are 3.73 gears popular?
So, why are 3.73 gears a popular upgrade for many car owners? In short, they offer improved acceleration and overall performance.
3.73 gears are a lower numerical ratio than the stock gears that come with most vehicles, which are usually in the range of 3.21 to 3.55. This means that with 3.73 gears, the engine turns the wheels more times for every revolution of the driveshaft. This leads to quicker acceleration and better overall performance.
Additionally, 3.73 gears are a popular choice for truck owners who tow heavy loads. The increased torque allows the truck to pull heavier loads more easily.
Benefits of 3.73 gears
Improved acceleration: As mentioned, 3.73 gears lead to improved acceleration. This can be especially noticeable in muscle cars that are built for speed.
Better towing capacity: For trucks, 3.73 gears can lead to better towing capacity. The increased torque allows the truck to pull heavier loads more easily.
Throttle response: With 3.73 gears, the engine responds more quickly to the throttle. This can be especially noticeable when passing on the highway or when merging onto a freeway.
Drawbacks of 3.73 gears
Fuel economy: One drawback to 3.73 gears is that they can lead to decreased fuel economy. The increased torque and quicker acceleration can lead to more fuel being burned during normal driving.
Top speed: 3.73 gears can also limit the top speed of a vehicle. This is because the increased torque doesn’t allow for the engine to spin as fast before hitting the redline.
Noise: Finally, some people have reported increased noise and vibration with 3.73 gears. This may be due to the increased stress on the drivetrain.
Conclusion
In summary, 3.73 gears are a popular upgrade for many truck and muscle car owners who want to improve their acceleration and overall performance. They offer benefits such as improved acceleration, better towing capacity, and quicker throttle response. However, they can also have drawbacks such as decreased fuel economy, limited top speed, and increased noise and vibration. Ultimately, whether or not to upgrade to 3.73 gears is a personal choice that depends on your specific needs and preferences.
