What is 3.73 rear end gear ratio?
The rear end gear ratio is a crucial aspect of a vehicle's drivetrain that significantly impacts its performance, fuel efficiency, and overall driving experience. In this article, we will delve into what a 3.73 rear end gear ratio means, its implications for your vehicle, and why it matters for both everyday driving and performance enthusiasts.
What is a Rear End Gear Ratio?
The rear end gear ratio refers to the ratio of the number of revolutions the driveshaft makes to the number of revolutions the wheels make. It is a critical component in determining how power is transferred from the engine to the wheels. A lower gear ratio (like 3.08) means the engine turns more times for each wheel revolution, while a higher gear ratio (like 4.10) means the opposite.
Understanding the 3.73 Gear Ratio
A 3.73 rear end gear ratio indicates that for every 3.73 revolutions of the driveshaft, the wheels complete one full revolution. This ratio strikes a balance between performance and fuel efficiency, making it a popular choice for various vehicles, especially trucks and performance cars.
Benefits of a 3.73 Gear Ratio
- Improved Acceleration: A 3.73 gear ratio allows for quicker acceleration, making it ideal for towing and hauling heavy loads.
- Better Torque Delivery: This ratio provides enhanced torque at lower speeds, which is beneficial for off-road driving and steep inclines.
- Balanced Fuel Economy: Compared to higher ratios, a 3.73 offers a good compromise between power and fuel efficiency, especially on highways.
When to Consider Changing Your Gear Ratio
Changing your vehicle's gear ratio can be beneficial in several scenarios:
- If you frequently tow heavy loads and need more torque.
- If you have upgraded your engine or installed larger tires, which can affect your vehicle's performance.
- If you want to enhance your vehicle's acceleration for performance driving.
Conclusion
In summary, a 3.73 rear end gear ratio is an excellent choice for those looking to balance performance with fuel efficiency. Whether you're a daily driver or a performance enthusiast, understanding your vehicle's gear ratio can help you make informed decisions about modifications and maintenance.

Frequently Asked Questions
What's the best rear-end gear ratio?
The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy. This is a good ratio for the occasional towing or hauling individual. For a person who tows more often, and heavier loads, the 3:73 or 4:10 may be more appropriate.
What gear ratio is best for gas mileage?
Best MPG ratio
If getting the best fuel economy is priority, then choose the lowest numerical number offered, such as 3.08, 3.23 or 3.31.
What gets better gas mileage, 3.73 or 4.10 gears?
a 4.10 has a huge impact on engine rpm because you are selecting second gear with a 3.73 to pull the grade, but you can hit third gear with a 4.10. Your engine speed is about 1,000 rpm lower, so temperatures under hood are going to be significantly lower. Higher numerical ratios often increase fuel consumption.
What gear ratio is best for towing?
The higher the ratio, the more revolutions per minute. Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.
Is a 3.73 axle good for towing?
The 3.73 will tow 8k lbs anywhere you want to go without needing more power or gear. The 4.30 is unnecessary if you dont ever intend to tow heavy. The 3.73 is still rated to tow the heaviest 2 axle 5th wheels on the market. Think of it more like this. With 3.73s it is like you have 1 extra gear vs 4.30s.
What gear ratio do I need for 35 inch tires?
Gear Ratio / Tire Size Table
| GEAR RATIO | ||
|---|---|---|
| T I R E D I A M E T E R | 4.56 | |
| 34" | 2929 | |
| 35" | 2845 | |
| 36" | 2766 |
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 most comfortable gear ratio?
For flat places, a ratio of 2.6 to 3.0 is ideal for most people. The lower value of this range, with a cadence of 90 rpm, will allow us to ride around 30km/h, while the upper, 34km/h. If you're just starting out on your adventure on a single speed or fixed gear bike, a gear ratio of around 2.7-2.8 will be ideal.
What is the best axle ratio for pulling?
between 3.55 and 3.73
The higher the ratio, the more revolutions per minute. Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.
What gear ratio gives more power?
For example, a lower gear ratio will provide more torque and better acceleration, while a higher gear ratio will provide less torque but better fuel efficiency. By selecting the right gear ratios for your vehicle, you can optimize its power and torque to meet your specific driving needs.
