Final Drive Ratio: 3.5 Transmission × 4.56 Axle
A 3.5:1 transmission ratio combined with a 4.56:1 axle ratio gives an overall final drive ratio of 15.96:1.
How to use this tool
- Look up your selected transmission gear ratio (e.g. 3.50:1 for 1st gear).
- Find the axle ratio from the vehicle specs or differential tag.
- Multiply them together to get the overall drivetrain ratio.
Multiplying a 3.5:1 transmission gear ratio by a 4.56:1 axle ratio yields an overall final drive ratio of 15.96:1.
Frequently asked questions
- What is the final drive ratio?
- The final drive ratio is the product of the transmission gear ratio and the axle ratio. It represents how many times the engine turns for each turn of the wheels.
- How does axle ratio affect towing?
- A numerically higher axle ratio (e.g. 4.10 vs 3.08) increases pulling torque, making it better for towing, but reduces highway fuel economy.
