4) 3.92 has 3 unique lower gears 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.
Is 3.92 or 3.55 gear ratio better?
The 3.92 axle ratio is actually better on fuel for city driving, less effort to go from stop to city driving speed. The 3.21 gets better highway mpg.
Is a 3.92 gear ratio good for towing?
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 difference between 3.55 and 3.92 gears?
3.92 is about 10% lower than the 3.55 with the same size tire. With the same rearend ratio the standard 17" wheels and tires are effectively about 6% lower geared than the 20". So you can get about halfway between the two ratios depending upon what you choose for wheel and tire size.
What is the best axle ratio for fuel economy?
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.
41 related questions foundWhat is the difference between 3.21 and 3.92 axle ratio?
From the speed 31-38 MPH, 3.21 has higher final drive ratio over 3.92 (15.12 vs 12.31) until it has to shift to 2nd gear at 38MPH. From the speed 39-47 MPH, 3.92 has higher final drive ratio over 3.21 (12.31 vs 10.10) until it has to shift to 3rd gear at 47 MPH.
What gear ratio is best for towing?
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.
Does gear ratio affect horsepower?
A higher numeric axle ratio (4.11:1) keeps the engine running in the higher horsepower range, thus improving performance.
Is it better to have a higher or lower gear ratio?
Gear ratios can be boiled down to a single statement: Higher ratios (with a lower numerical value) give better torque/acceleration and lower ratios allow for higher top speeds and better fuel economy. Higher ratios mean the engine has to run faster to achieve a given speed.
What is the difference in rear end gear ratios?
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.
How do I choose the right gear ratio?
TRACK-OUT GEARING
The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.
Is lower gear ratio better for towing?
Performance: Looking again at the ratios used above, the higher 3.55 ratio indicates faster acceleration whether the truck's empty or loaded. 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.
How does axle ratio affect acceleration?
A lower (taller) gear ratio provides a higher top speed, and a higher (shorter) gear ratio provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential.
Is 3.92 a good axle ratio?
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 3.55 rear axle ratio?
The axle ratio tells you the number of revolutions the drive shaft makes compared to the rear axle. For a 3.55 axle ratio, the drive shaft will turn 3.55 times for every one revolution of the tire.
What is the Gcwr of a Ram 1500?
The RAM 1500 weight rating (known as GVWR, or Gross Vehicle Weight Rating) is about 4,800 pounds. That figure varies depending on factors like trim level, cargo weight, and passengers — so how much does the RAM 1500 weigh? Groundbreaking design features allow the 1500 to earn a GVWR between 6,800 and 7,800 pounds.
Does higher gear mean faster bike?
Just remember that larger gears at the rear mean easier pedalling but more torque, and larger gears at the front mean harder pedalling but more speed.
Do front and rear gears have to match?
Yes they must match. Picture your rear axle doing 50 and your front doing 40 or 60. Your transfer case will not last long.
What rear end gears should I use?
If it's a daily driver, chances are you'll want to keep your gear ratio at 3.23 or below for optimal performance and lower cruising RPMs. For street and strip applications, a popular choice ranges between 3.42s and 3.90s, giving you that extra oomph on the track while maintaining a tolerable cruising RPM on the street.
Do more gears make car faster?
The simple answer is yes. More aggressive gearing creates a quicker car but not a faster car. A gearing change will have a noticeable affect on your car. If you swap in taller rear gears, you can gain some top-end speed, making your car faster, but you're going to be a bit slower leaving from a stop.
What makes a car accelerate faster?
In terms of acceleration, torque plays a bigger role in how quickly your car accelerates. That's because the torque is a result of the force the pistons generate and at what speed. The quickest vehicles can generate high levels of this torque force at relatively low rpm. This allows the vehicle to accelerate quickly.
What is the best gear ratio for power?
1 to 1 or direct gear, is always the best gear for fuel mileage, quietness, cooler temperatures in the transmission, and more pulling power. However, to run in direct gear, the rear gears must be either 2.64, 2.47, 2.21 and I think there is even a higher gear than the 2.21. The average speed today is 70 miles per hour.
What does GVWR mean?
The GVWR is the Gross Vehicle Weight Rating, or the most weight that your vehicle can safely handle. In the past, you may have seen “Gross Axle Weight Ratings” or GAWR, but the modern gross vehicle weight rating is more precise.
Does bigger tires change gear ratio?
When changing gears for taller tires, you are heading to a numerically higher gear ratio. The higher the gear ratio, the smaller the pinion gear. You do not want go too low in an effort to increase power to the wheels and/or relieve stress in the rest of the drivetrain.
Is a 3.23 axle ratio good for towing?
The lower the ratio, the better the fuel economy and speed but lower the towing power. The 2021 Silverado 1500 provides two axle ratios: 3.42 and 3.23. If you're looking for a higher towing capacity, choose the 3.42 rear axle ratio. If it's optimal fuel economy you're after, choose the 3.23.
