* 4.10:1: This was a popular choice, offering good low-end torque for heavy hauling and off-roading.
* 4.56:1: Even lower gearing, providing even more pulling power at the expense of higher engine RPM at highway speeds.
* Other possibilities: While less common, there might have been other ratios available depending on the specific configuration.
To find the exact gear ratio for *your* specific 1975 Dodge Power Wagon, you'd need to:
* Check the Vehicle's Documentation: Look for the original build sheet or owner's manual. This will often list the axle ratio.
* Check the Differential Tag: The differential itself (located in the rear axle) usually has a tag stamped with the gear ratio. You might need to jack up the truck to see it.
* Contact a Dodge Parts Specialist or Enthusiast: They might have access to resources or databases to help you determine the ratio based on the truck's VIN.
Without knowing your specific truck's VIN or build details, it's impossible to give you a definitive answer.
