The options for a 1500 are 3.21, 3.55, and 3.92:1.
The options for 2500 and 3500 are 3.42, 3.73, 3.83, and 4.10:1.
The 4500,5500 options are 4.10, 4.44, and 4.88:1.
That will vary on the gear your are in and what the rear axle gear ratio is.
Could be 3.55 or 4.10
Most were 3.55:1
The most likely ratio is 3.55-1.
If the front is 3.55, then the rear needs to be 3.55
3.55 or 4.10 : 1
Could be 3.55, or 4.10:1
Could be 3.21, 3.55, or 3.92:1
There isn't a position that tells the gear ratio. The dealer can enter the VIN in their computer system and pull up the build codes to see what ratio it was built with.
Depends on gear ratio but you can expect 15MPG or less
There are four ways to find a ratio. 1 A dealer can normally tell from the vin number. 2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement info. 3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires. 4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.
There isn't a specific digit for the gear ratio. The last nine digits are vehicle specific, the dealer can input those digits in their computer system to get the build list of the truck. The ratio will be listed there.
