The axle ratio of a Dodge Challenger can vary depending on the specific model and options chosen. There are several different axle ratios available for the Challenger, including 3.23, 3.73, 3.90, and 3.09. The specific axle ratio can also depend on whether the vehicle has a manual or automatic transmission. For example, the base R/T model with a manual transmission may have a 3.90 axle ratio, while the R/T with an automatic transmission may have a 3.09 axle ratio. It’s important to note that these are just a few examples, and there may be other axle ratios available for different Challenger models and years.

Is 3.21 or 3.92 better for towing?
5) Speed range that 3.21 is better at towing: 31-38 MPH, 48-57 MPH. 6) Speed range that 3.92 is better at towing: 0-30 MPH, 39-47MPH, 58-70 MPH. 2) 3.21 has “an extra” overdrive gear: The 8th gear in 3.92 is the 7th gear in 3.21, thus effectively mean the 8th gear in the 3.21 is an extra gear to the 3.92.
How do I find my axle ratio?
The easiest way to find an axle ratio is to check the spec sheet in your owner’s manual. It may also be listed on a sticker that you can find on the outside of your differential.
What is a 3.73 axle ratio good for?
A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow a heavier trailer than one with 3.55 or 3.21.
Why are 3.73 gears good?
In a sports car, 3.73 gears will offer better acceleration while retaining top speed when compared to 3.55 gears that come factory on many sports cars.
Is a 3.92 rear axle ratio good?
In short, yes. Which axle ratio you go with will affect your truck’s towing capability, but fuel economy will change too. A higher axle ratio (like the 3.92 we mentioned earlier) will allow for higher towing capability, but it requires higher engine rpm for any given speed and then results in lower fuel economy.
What is the towing capacity of a 3.21 rear axle ratio?

What is better 3.73 or 4.10 gears?
What Gear Ratio Is Best For Torque? Typically, the shorter the gear, the higher the torque. When looking at 3.73 vs 4.10 gears, 4.10 gears are going to offer higher torque.
What is the gear ratio of the scat pack rear end?
So the gear ratio in a dodge scat pack is 3.09 or 3.90.
What is the difference between a 4.10 and 3.73 rear end?
What is the difference between a 3.73 and a 4.10 axle ratio? 4.10 gears will give you more toque for pulling at lower speeds, as it is lower geared, but it does cost you in fuel efficiency. I prefer 3.73, as it gives plenty of torque for pulling, but doesn’t cost you as much fuel mileage.
Which is better 3.21 or 3.92 axle ratio?
In very general terms, the 3.21 would be expected to yield a bit better fuel economy at a slight acceleration penalty; the 3.92 a bit better acceleration at a slight economy penalty.
