Ram 3.73 Vs 4.10 Gears: Which One Is Better?

Is there any difference between Ram 3.73 and 4.10 gears? Well, there are several differences, but in common, the 4.10 gears have quicker acceleration than the 3.73 gears.

The axle gear ratio Ram 3.73 vs 4.10 gears has been the subject of many debates in the past. Many people believe that the 3.73 gear is better than the 4.10 gear because it offers a higher top speed. Others believe the 4.10 axle ratio offers better performance because it offers a higher gear range and more torque.

However, we’ve compared these two based on performance and other key factors such as RPM, torque, fuel economy, towing capacity, etc. The following comparison will help you choose the suitable gear for your vehicle.

There are a few important differences between these two gears found in most modern cars. A comparison table of it is given below.

Fuel EconomyBetterDecreased

Both ratios provide excellent results but have different performance requirements for different vehicle models. Below based on specific factors, the outcomes for using these gears are provided.


There is a lot of debate on whether or not 4.10 gears are better than 3.73 gears in terms of acceleration. Some people say that the extra inch of gear that the 4.10 ratio offer can make a big difference in the speed at which a vehicle can travel, while others claim that the increased wear and tear on the transmission will negate any benefits that could be achieved from upgrading.

Acceleration performance between 3.73 and 4.10 can differ drastically. All vehicle types were tested on a calibrated instrumented testing track with a 50 km/h (30 mph) barrier speed. The results indicate that at 50 km/h (30 mph), the 4.10 axle ratio provides significantly greater acceleration than the 3.73 gear. Here, the 4.10 ratio revolves higher than the 3.73. The greater spin correlates to a stronger centripetal acceleration, which results in a quicker 4.10 acceleration.

Top Speed

The Cummins 3.73 gears provide a higher vehicle top speed, but it also requires more effort from the driver to maintain a steady pace. The 4.10 gear ratio offers lower vehicle speeds, but it can be easier to maintain a steady pace because the engine works less hard. It’s important to consider the type of driving you will be performing when selecting your gear ratio, as well as your vehicle’s maximum speed.


Vehicles equipped with a 3.73 gear ratio typically have a higher RPM (Revolutions per Minute) than those with a 4.10 ratio. This is because the 3.73 allows for more engine speed before the gears start to mesh, resulting in a higher RPM. The Ram 2500 4.10 gears, on the other hand, has fewer gears and therefore requires the engine to spin at a slower RPM to achieve the same engine speed.

The higher RPM allows the engine to run at a higher speed, which improves fuel economy and emissions. Additionally, the increased speed allows for an easier turn in traffic, making it easier to get around obstacles. It is important to bear in mind that this difference is only significant when traveling at high speeds, as lower speeds are largely unaffected by the difference between the gears.

Towing Capacity

The 3.73 gear has fewer teeth than the 4.10 gear, which means that it can move less weight with each rotation. This is important because it means that the towing capacity of a vehicle with a 4.10 ratio is greater than a vehicle with a 3.73 ratio.

In addition, the 4.10 runs smoother than the 3.73, which makes it quieter when towing a heavy load. For example, suppose the gearing on a vehicle allows for towing up to 5,000 pounds; with the 4.10 ratio additional 2000 pounds can move. However, the 3.73 ratio gives better mileage within the same weight towing.


Vehicles with a 4.10 typically have more torque and are better suited for high-performance applications, such as racing or off-road use. In particular, a 3.73 requires less torque than a 4.10 to move a car or truck forward and more torque to move it backward. This is because a 3.73 has a shorter ring gear than a 4.10.

Higher torque provides many advantages over lower torque gears. For example, higher torque gears can resist wear and tear better, helping your car or truck maintain its performance for longer. Additionally, this torque is often easier to reverse than lower ones, making them perfect for use in manual transmission vehicles.

Fuel Economy

Compared to using the Ram 4.10, using the 3.73 gear offers better fuel economy in most situations. The main reason for this is that the 3.73 are geared lower than the 4.10, which allows more revolutions per minute (RPM) to be achieved with less torque and power.

This means that less fuel is needed to push the vehicle through a given distance, which can result in significant savings on gasoline bills over time.

Additionally, 4.10 gears are often found in heavier vehicles that require more torque to move them quickly, such as trucks and SUVs. Also, it allows the engine to make more horsepower at lower gears, which results in increased acceleration and fuel economy.

Frequently Asked Questions (FAQs)

Are 3.73 or 4.10 gears better?

The answer depends on the user’s need. In most cases, people usually chose 3.73 over 4.10.

Is a 4.10 gear ratio good for towing?

A 4.10 axle ratio is an ideal gear for towing. The heavier loads can be smoothly shifted with this ratio in highway driving.

Are 3.73 gears good for towing?

The vehicle with 3.73 will give a pretty average towing performance. Due to high RPM, it will need more engine power and fuel as well.

What are 4.10 gears good for in a truck?

The 4.10 are easier to change, and it doesn’t need much effort for puling high work. So, hauling and towing are quite simple with it. Also, they look nice and modern on trucks, adding a bit of style while still providing performance benefits.


At first glance, it might seem that the 4.10 gears would be a better option for your vehicle. However, if you are looking for better fuel economy or achieving higher top speeds, in that case, you may want to consider switching to a gear ratio of Ram 3.73 over a 4.10. The 3.73 is known to be more efficient than the 4.10.

On the contrary, for higher acceleration and towing capacity for trucks or SUVs, go for a 4.10 axle ratio.

Ultimately, it’s up to you to decide which gear you want to use in your vehicle. The difference in gear ratios will affect how quickly your vehicle can accelerate and reach its top speed. When you select gears, it is important to take into account you’re driving style as well as the terrain you will be traveling on. Hopefully, the article on Ram 3.73 vs 4.10 gears was useful for you.
