What is the best rear axle ratio for Ford Transit?

The best rear axle ratio for a Ford Transit depends on your specific needs and usage. Different axle ratios offer different benefits in terms of towing capacity, fuel efficiency, and overall performance. Here are some considerations to help you make a decision:
– Towing Capacity: If you plan to tow heavy loads or frequently tow trailers, a higher axle ratio, such as 4.10, may be beneficial. Higher ratios provide more torque and better acceleration, making it easier to tow heavy loads.
– Fuel Efficiency: If fuel efficiency is a priority and you don’t require a high towing capacity, a lower axle ratio, such as 3.31, may be a better choice. Lower ratios allow the engine to run at lower RPMs, resulting in better fuel economy during highway driving.
– Terrain and Off-Roading: If you frequently drive in hilly or mountainous terrain or plan to use your Ford Transit for off-roading, a lower axle ratio may provide better performance. Lower ratios offer more torque and better low-speed acceleration, which can be advantageous in challenging terrains.
– Personal Preference: Ultimately, the choice of rear axle ratio depends on your personal preferences and priorities. Consider your specific needs, such as towing requirements, fuel efficiency goals, and the type of driving you’ll be doing, to determine the best axle ratio for your Ford Transit.
It’s important to note that the axle ratio is not the only factor that affects towing capacity and fuel efficiency. Other factors, such as engine power, transmission, and vehicle weight, also play a role. It’s recommended to consult the vehicle specifications and consult with a Ford dealer or expert to ensure you make an informed decision based on your specific requirements.
Please keep in mind that the information provided is based on general knowledge and may not be specific to the latest Ford Transit models. It’s always a good idea to consult the official Ford website or contact a Ford dealership for the most up-to-date and accurate information regarding rear axle ratios for the Ford Transit.

Which is better 3.21 or 3.92 axle ratio?

For towing, From the speed 0-30 MPH, 3.92 has higher final drive ratio over 3.21 (18.46 vs 15.12) until it has to shift to 2nd gear at 30MPH. 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.

What is the difference between 4.7 and 3.73 axles?

Your engine is going bang more often with 4.7 than with 3.73 for any given speed. So, unless that additional torque is necessary to move something, the vehicle, with or without a trailer, etc. you are turning and burning more fuel for a given speed.

Is a 3.42 rear axle ratio good?

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.

What is the difference between 3.55 and 3.73 axle ratio?

1:3.73 is about 5% lower than 1:3.55. So if you change from 3.55 to 3.73 , you’re going 5% slower when you hit the same gear change – if you normally change first to second at 30 mph, now you change at 28.5 mph, second to third at 50 mph -> now at 47.5 mph, etc.

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.

Is a 3.42 rear end good?

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.

What is the advantage of 3.73 gears?

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.

Should I get 3.73 or 4.10 gears?

There is only a 10% difference between 4.10 and 3.73 gears. Unless you need to tow heavy loads, I would keep the 3.73 gears. Or maybe if you are going to big, big tires. Otherwise you probably won’t notice the difference.

Is a 3.92 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 best rear differential ratio?

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.
