Which axle ratio is best?
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 3.92 good for towing?
Go with the 3.92 gearing and the tow rating jumps up to 11,540 pounds — a massive 3,100-pound difference. 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 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.
