Revolution Gear & Axle 2021+ Ford Bronco 220mm/210mm 4.56 Ratio 2-Cut Gear Package

If you're looking to significantly improve your 2021+ Ford Bronco's off-road capability or towing power, changing the differential gear ratio is a key step. This Revolution Gear & Axle package is designed to give your Bronco a 4.56 gear ratio, which is a popular choice for those running larger tires or needing more torque for hauling. This ratio offers a good balance, providing better acceleration and pulling power without excessively increasing engine RPM at highway speeds compared to even lower ratios.

This kit includes everything needed for a professional installation of the 4.56 ratio gears for both the 220mm front and 210mm rear differentials found in the 2021 and newer Ford Bronco. Revolution Gear & Axle is known for well-built drivetrain components, and this package reflects that with precision-cut gears designed for durability and smooth operation. The 2-cut design refers to the manufacturing process that ensures proper tooth contact and load distribution, which is critical for the longevity of your differential under demanding conditions. Installing a new gear set like this is a complex job that requires specialized tools and knowledge, often involving setting backlash and pinion depth correctly to avoid premature wear.

When upgrading your Bronco's gearing, it's important to consider other drivetrain components. This package is designed to work with the factory differentials, but ensure you have the necessary installation hardware and fluids. A proper gear oil with the correct viscosity and friction modifiers is essential for breaking in the new gears and ensuring optimal performance and lifespan. Consult with a professional installer or the manufacturer's guidelines for the recommended break-in procedure after installation.
