What To Know
- An axle ratio is a numerical value that represents the relationship between the number of revolutions the driveshaft makes for every revolution of the wheels.
- This is because the higher axle ratio allows the wheels to turn more times for each revolution of the driveshaft, resulting in increased torque at the wheels.
- Yes, it is possible to change the axle ratio on a Ram 3500, but it is a complex and expensive procedure that should be performed by a qualified mechanic.
When it comes to heavy-duty pickup trucks, the Ram 3500 reigns supreme. With its formidable capabilities and impressive performance, it’s a workhorse that can handle any task you throw at it. However, when it comes to choosing the right axle ratio for your Ram 3500, the decision between 3.73 and 4.10 can be crucial. In this blog post, we’ll dive deep into the differences between these two axle ratios, helping you make an informed choice based on your specific needs.
Understanding Axle Ratios
An axle ratio is a numerical value that represents the relationship between the number of revolutions the driveshaft makes for every revolution of the wheels. A higher axle ratio, such as 4.10, means that the wheels turn more times for each revolution of the driveshaft. Conversely, a lower axle ratio, such as 3.73, means that the wheels turn fewer times for each revolution of the driveshaft.
Performance Differences
The primary difference between the 3.73 and 4.10 axle ratios is their impact on performance. Here are the key differences to consider:
Acceleration and Towing
A 4.10 axle ratio provides better acceleration and towing capabilities compared to a 3.73 axle ratio. This is because the higher axle ratio allows the wheels to turn more times for each revolution of the driveshaft, resulting in increased torque at the wheels. As a result, the truck can accelerate more quickly and tow heavier loads.
Fuel Efficiency
On the other hand, a 3.73 axle ratio offers better fuel efficiency than a 4.10 axle ratio. This is because the lower axle ratio reduces the number of times the wheels turn for each revolution of the driveshaft, resulting in lower engine RPMs at cruising speeds. As a result, the truck can achieve better fuel economy on the highway.
Off-Road Performance
For off-road enthusiasts, a 4.10 axle ratio is generally preferred. The higher axle ratio provides increased torque at the wheels, allowing the truck to navigate challenging terrain more easily. It also provides better control when driving on slippery or uneven surfaces.
Choosing the Right Axle Ratio
The best axle ratio for your Ram 3500 depends on your specific needs and usage patterns. Here are some guidelines to help you make the right choice:
If you frequently tow heavy loads or drive in mountainous areas:
A 4.10 axle ratio is recommended for improved acceleration and towing capabilities.
If you drive mostly on the highway and prioritize fuel efficiency:
A 3.73 axle ratio is a better choice for maximizing fuel economy.
If you engage in off-road activities:
A 4.10 axle ratio is preferred for enhanced torque and improved off-road performance.
Additional Considerations
In addition to performance, there are a few other factors to consider when choosing between a 3.73 and 4.10 axle ratio:
Tire Size
Larger tires may require a higher axle ratio to maintain optimal performance.
Engine Configuration
Different engine configurations may have different recommended axle ratios.
Payload Capacity
The payload capacity of your truck may also influence the best axle ratio choice.
The Bottom Line: Making the Right Decision
Choosing the right axle ratio for your Ram 3500 is essential for maximizing its performance and efficiency. By understanding the differences between 3.73 and 4.10 axle ratios, you can make an informed decision based on your specific needs. Whether you prioritize acceleration, fuel economy, or off-road capabilities, there’s an axle ratio that’s perfect for your truck.
