The ideal differential ratio for a Ford F100 with 15-inch tires and an automatic gearbox typically falls between 3.00:1 and 3.50:1, depending on your specific use case. A lower ratio (like 3.00:1) is better for highway driving and fuel efficiency, while a higher ratio (like 3.50:1) improves acceleration and towing capacity. It's essential to consider factors such as engine power, intended use, and driving conditions when selecting the right ratio. Always consult with a professional or refer to manufacturer recommendations for the best fit for your setup.
