What gear ratio does a 2013 Ram 1500 have?
The 2013 Ram 1500 has a gear ratio of 3.55:1 for its standard rear axle configuration. This gear ratio is designed to provide a balance between fuel efficiency and towing/hauling capability for the full-size pickup truck.
Understanding Gear Ratios
The gear ratio of a vehicle's differential refers to the relationship between the number of times the drive shaft rotates compared to the number of times the wheel rotates. A higher gear ratio, such as 3.55:1, means the drive shaft needs to rotate fewer times to turn the wheels once, providing more torque and power for towing and hauling heavy loads.
Lower gear ratios, such as 3.21:1 or 2.92:1, are typically found in vehicles focused more on fuel efficiency, as they require the drive shaft to rotate more times per wheel revolution, reducing the amount of work the engine has to do.
2013 Ram 1500 Gear Ratio Options
The 2013 Ram 1500 was available with the following rear axle gear ratio options:
- 3.55:1 (standard)
- 3.21:1 (available on some models)
- 3.92:1 (available on some models)
The 3.55:1 gear ratio was the most common configuration, as it provided a good balance between towing/hauling capability and fuel efficiency for the majority of Ram 1500 owners. Buyers who needed more towing power could opt for the 3.92:1 ratio, while those focused on maximizing fuel economy could choose the 3.21:1 ratio.
Factors Affecting Gear Ratio Choice
When selecting the appropriate gear ratio for a vehicle, manufacturers consider factors such as:
- Engine power and torque
- Intended use (towing, hauling, daily driving)
- Fuel efficiency targets
- Tire size
- Transmission type (automatic or manual)
The 2013 Ram 1500's gear ratio options were designed to meet the needs of a wide range of customers, from those who prioritize towing capacity to those focused on maximizing fuel economy.
What is the axle ratio of a 2013 Dodge Ram 1500?
Ram has a standard axle ratio of 3.21 on 2X4 trucks and 3.55 on 4X4 trucks and trucks with the diesel engine.
How do I tell what gear ratio my Ram 1500 has?
The ratio will be stamped on the outer circumference of the ring gear.
Which RAM gear ratio is best?
FACT: A 4.10 axle ratio is ideal for towing heavy loads in a mix of city and highway driving and when towing on varied or steep grades. A 4.10 axle ratio will provide improved acceleration in stop and go city traffic.
Will the VIN number tell me the gear ratio?
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.
What is the best rear axle ratio for a Dodge Ram 1500?
FACT: A 3.73 axle ratio is ideal for towing heavy loads on flat terrain and will produce increased fuel economy during steady-state, long-distance highway driving.
What is the gear ratio of the transmission on a Dodge Ram 1500?
The 8-speed transmission for the Ram 1500 has the following gear ratios: 4.69, 3.13, 2.10, 1.67, 1.28, 1.00, . 84, . 67. Each of the gears for speeds 4, 5, and 7 is about a 21% change to the next gear up except the change from 6th gear (ratio 1.00) to 7th is only 16%.
How do I find my transmission gear ratio?
Here's the formula for calculating gear ratio: (RPM x Tire Diameter Inches) / (Final Drive Ratio x Transmission Gear Ratio x 336) = Actual numerical gear ratio to the ground from every revolution of the engine.
Which RAM has a 3.92 rear axle ratio?
For example, consider a 2021 Ram 1500 crew cab in the Laramie trim level. It comes standard with a 3.21 ratio and offers optional 3.55 and 3.92 ratios.
How do I identify my RAM differential?
If the ID tag or stamp is missing or unreadable, differentials can be identified by the number of cover bolts, the distinctive shape of the cover, the number of ring gear bolts, and ring gear diameter. They can also be identified by whether the center section is an integral or dropout design.
What does 3.92 gears mean?
In terms of capability, the 3.92 gives you a higher max tow rating. The rating isn't particularly important, though. Practically speaking, the tow capacity of 1/2 tons is limited by payload. The advantage of the 3.92 gearing is getting moving when towing.
