What is a good rear end gear 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.

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.

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.

You don’t. That information is not contained in the VIN, UNLESS a specific model only gets one rear end ratio. VIN tells country of manufacture, vehicle make, class, engine type, size, date of manufacture, plant and serial number. That is the ONLY information contained by the VIN.

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.
