What is the axle ratio of a 2015 Silverado 1500?
The axle ratio is a crucial aspect of any vehicle's performance, particularly for trucks like the 2015 Chevrolet Silverado 1500. This article will delve into what axle ratio means, its significance, and the specific ratios available for the 2015 Silverado 1500, helping you make informed decisions about your vehicle's capabilities.
What is Axle Ratio?
The axle ratio refers to the relationship between the number of revolutions the driveshaft makes compared to the number of revolutions the wheels make. It is expressed as a ratio, such as 3.42:1. This means that for every 3.42 turns of the driveshaft, the wheels turn once. A higher axle ratio indicates more torque and better towing capacity, while a lower ratio can lead to better fuel efficiency.

- 3.08:1 - This ratio is ideal for those prioritizing fuel efficiency over towing capacity.
- 3.42:1 - A balanced option that provides a good mix of towing capability and fuel economy.
- 3.73:1 - This ratio enhances towing performance, making it suitable for heavy loads.
- 4.10:1 - Best for maximum towing capacity, this ratio is perfect for those who frequently haul heavy trailers.
Why Does Axle Ratio Matter?
Choosing the right axle ratio can significantly impact your driving experience. Here are a few reasons why it matters:
- Towing Capacity: A higher axle ratio allows for greater torque, which is essential for towing heavy loads.

Frequently Asked Questions
How do I tell what gear ratio my Chevy Vin has?
You don't. That information is not contained in the VIN, UNLESS a specific model only gets one rear end ratio. VIN tells country of manufacture, vehicle make, class, engine type, size, date of manufacture, plant and serial number. That is the ONLY information contained by the VIN.
How do I find the axle ratio on my Chevy Silverado 1500?
Identify your GMC or Chevrolet rear end gear ratio by the RPO Codes, usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box.
How can I tell what axle ratio my truck has?
To determine the axle ratio of your vehicle, locate the two-digit axle code first, then use your vehicle's towing guide to find the axle ratio that corresponds to that code. If your vehicle has a limited-slip differential, it will be noted as Limited Slip.
Is a 3.55 axle ratio good for towing?
As truck manufacturers produce transmissions using more gears, the axle ratios will also change. For example, a transmission with more gears might allow a truckmaker to offer a taller rear axle ratio (a 3.55 instead of 3.73) and still provide improved towing and hauling capabilities.
What is the towing capacity of the 3.42 rear axle ratio Chevy Silverado?
This truck can tow as much as 13,300 pounds.
What axle ratio gets better mileage?
The lower the number, the better fuel economy, and the higher the number the more towing power you have, but fuel economy suffers. For instance, a 3:31 gets better fuel economy than a 3:73. On the other hand, a 3:73 or perhaps a 4:10 will tow much more, while fuel economy greatly drops.
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.
Is a 3.73 axle ratio good for towing?
3.73 is preferred for towing. You will find that the fuel economy difference of running at 75mph instead of 80mph will make a bigger difference than gear ratio. Drag is an exponential relationship to speed and anything above around 60mph in a truck really makes a difference in fuel economy.
Is a 3.42 axle ratio good for towing?
3.42 are Fine, just might make the engine huff and puff a little more uphill and on takeoff but with that 5.3, you'll be fine and I would suggest this, My friend is running a towing company at Nyc Manhattan Towing Service, he suggested to me this.
Which is better, 3.73 or 4.10 axle ratio?
ARE 3.73 OR 4.10 GEARS BETTER? Use this rule of thumb: The shorter the gear ratio (higher number), the easier it will be for the vehicle to start moving and accelerating! This will, however, lower the top speed of the vehicle.
