What is the rear axle ratio of a Dodge Charger?
The rear axle ratio of a Dodge Charger is a crucial specification that determines the vehicle's performance and fuel efficiency. This 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 rear wheels rotate.
What is the Rear Axle Ratio?
The rear axle ratio is a numerical value that represents the number of times the driveshaft rotates for every single rotation of the rear wheels. For example, a rear axle ratio of 3.73:1 means that the driveshaft rotates 3.73 times for every single rotation of the rear wheels.
The rear axle ratio is an important factor in a vehicle's performance and fuel efficiency. A higher ratio, such as 4.10:1, will provide more torque and acceleration but will also result in lower fuel economy. Conversely, a lower ratio, such as 3.21:1, will provide better fuel efficiency but less acceleration.
Dodge Charger Rear Axle Ratios
The Dodge Charger is available with several different rear axle ratio options, depending on the specific model and engine configuration. Here are some common rear axle ratios found in Dodge Chargers:
- 3.21:1 - Available on some V6 models for improved fuel efficiency
- 3.07:1 - Available on some V6 models for a balance of performance and efficiency
- 3.45:1 - Common on V8 models for a good balance of power and fuel economy
- 3.73:1 - Available on high-performance V8 models for increased acceleration and towing capacity
- 4.10:1 - Found on the high-performance Dodge Charger Hellcat models for maximum acceleration and power
The rear axle ratio is an important specification to consider when purchasing a Dodge Charger, as it can significantly impact the vehicle's performance and fuel efficiency. Drivers who prioritize acceleration and power may opt for a higher ratio, while those focused on fuel economy may choose a lower ratio.

What is the rear axle ratio of the scat pack?
Brochure says 3.09 and 3.90 are standard.
What is a 3.73 axle ratio good for?
The higher the ratio, the more revolutions per minute. Towing: For pickup trucks released after 2010, the best axle ratio for towing falls somewhere between 3.55 and 3.73. This range provides good acceleration for V8 gas and diesel engines.
What is the ratio of a gear shift?
Gear Basics
The gear ratio is the number of turns the output shaft makes while the input shaft turns one time. If the gear ratio is 2:1, then the smaller gear is turning two times while the larger gear turns just once. It also means that the larger gear has twice as many teeth as the smaller gear.
What rear axle ratio is best?
The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy. This is a good ratio for the occasional towing or hauling individual. For a person who tows more often, and heavier loads, the 3:73 or 4:10 may be more appropriate.
Which is better, 3.21 or 3.92 axle ratio?
The standard 3.21 axle ratio then gets you a maximum tow rating of 8,440 pounds. Go with the 3.92 gearing and the tow rating jumps up to 11,540 pounds — a massive 3,100-pound difference.
What is the 3.92 rear axle ratio challenger?
A typical final drive ratio in a Challenger is 3.92:1. This means for every time the driveshaft spins 3.92 times, the tires rotate once. By moving to a lower gear ratio (higher numerically) you will increase throttle response but lower top speed.
What does 3.21 rear axle ratio mean?
Axle Ratios Vary From Vehicle to Vehicle
For example 3.21:1, meaning that the driveshaft must make 3.21 rotations to rotate the axle one full turn. More commonly, though, you'll see this simplified to just 3.21 in automaker marketing materials. Pickup trucks tend to offer buyers a choice of axle ratios.
What is 3.42 gear ratio good for?
For instance, the 3.42:1 ratio included on many Canyon V-6 and Sierra 1500 models offers a good all-around blend. That said, if you regularly tow heavy trailers or prefer a peppier feel in acceleration, consider a truck equipped with a higher numeric axle ratio.
