* Engine size: Larger engines often came with lower gear ratios (e.g., 3.55, 3.73) for better highway fuel economy. Smaller engines might have higher ratios (e.g., 3.92, 4.10) for better acceleration.
* Transmission type: The transmission (automatic or manual, and the number of gears) influences the gear ratio choice.
* Trim level: Higher trim levels sometimes had different axle ratios.
* Towing package: Trucks equipped for towing often had lower numerical gear ratios for better towing capacity.
* Specific options chosen by the original buyer: Even within a specific model and engine, the buyer might have had options that altered the rear end gear.
To find the gear ratio of a *specific* 2005 Dodge Ram, you need to:
1. Check the vehicle's build sticker (usually located on the driver's side doorjamb). This sticker often lists the axle ratio.
2. Look at the vehicle's owner's manual. It might specify the rear axle ratio.
3. Check the differential tag. This is a tag located on the differential housing itself. It will give you the gear ratio.
4. Have a mechanic or tire shop inspect the vehicle. They can easily determine the gear ratio.
Without knowing the specific configuration of the 2005 Dodge Ram, it's impossible to give a definitive answer.
