What gear ratio do I need for truck?
Two common base axle ratios for trucks are 3.08 and 3.42. A 3.73 ratio is suitable for regular light towing.

What is the axle ratio of my truck?

The calculation uses the number of teeth in the ring gear and divides it by the number of teeth in the pinion gear to provide you with a “[result] to 1” ratio. For example, if the pinion gear has 41 teeth, and the ring gear has 11 teeth, the ratio would be calculated as 41/11, which is equal to 3.73 = 3.73:1.
What rear axle ratio is best for fuel economy?
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.
Is 3.55 or 4.10 gears better?
If towing less than that and / or drive a lot of empty miles, 3.55 is better. Actual towing ratings are 27,300 lbs for 3.55 or 31,300 lbs for the 4.10. The 3.55 will certainly return better unloaded fuel economy than the 4.10 and be slightly quieter inside.
