What is an Axle Ratio?
The axle ratio, also known as the final drive ratio, is the relationship between the number of times the driveshaft rotates compared to the number of times the wheels rotate. It determines the amount of torque and speed delivered to the wheels. A higher axle ratio, such as 3.42:1, provides more torque for towing and hauling, while a lower ratio, like 3.08:1, prioritizes fuel efficiency and highway driving performance.
2015 Silverado 1500 Axle Ratio Options
The 2015 Chevrolet Silverado 1500 was available with the following axle ratio options:
- 3.08:1 - This is the standard axle ratio for most Silverado 1500 models, providing a balance between fuel efficiency and towing/hauling capability.
- 3.42:1 - This higher axle ratio is often selected for models equipped with the 5.3L V8 engine, as it provides more torque for improved towing and hauling performance.
The specific axle ratio of a 2015 Silverado 1500 can be determined by checking the vehicle's build sheet or contacting the dealer. The axle ratio is an important factor to consider when selecting a truck for your needs, as it can significantly impact the vehicle's capabilities.
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.
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.
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.
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.
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.
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.
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.
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 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.
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.
