Complete Gear Package with Master Install Kit

Upgrading your truck’s gearing is one of the most effective ways to restore lost power, improve towing performance, and enhance off-road capability—and the Revolution Gear & Axle 4.56 Ring and Pinion Gear Package is designed to do just that. Whether you're compensating for larger tires, improving low-end torque, or just replacing worn-out gears, this package ensures your 1993-2009 Ford F-250 or F-350 is equipped for the job. This kit includes both front and rear ring and pinion gears, along with a master install kit featuring premium Koyo bearings and all the necessary components for a precise and reliable setup. The 4.56 gear ratio strikes a great balance between performance and drivability. If you've upgraded to 35-inch tires or larger, your stock gearing is likely struggling to keep up. Higher gears like 3.73s or 4.10s may feel sluggish, causing your truck to work harder to maintain speed, especially when towing or climbing hills. By switching to 4.56s, you’re reclaiming lost acceleration, improving throttle response, and optimizing torque delivery, making it easier to tow heavy loads, navigate rough terrain, and handle stop-and-go traffic with ease. While numerically higher gears like 4.88s or 5.13s provide even more low-end power, they can result in higher RPMs at highway speeds. The 4.56 ratio keeps your engine in a more efficient powerband, offering strong pulling power without excessive revving on long drives.

High-Quality Construction for a Precise Fit

A complete gear package like this ensures that both front and rear differentials are properly matched, which is essential for four-wheel drive operation. Running mismatched ratios can cause drivetrain binding and serious mechanical damage. Upgrading both at the same time not only keeps your truck running smoothly but also saves time and money compared to installing them separately. The included master install kit further simplifies the process, providing Koyo bearings, shims, seals, gaskets, gear marking compound, and hardware to ensure a precise and quiet setup. Properly installing new gears requires meticulous adjustment, and having all the right components on hand makes a significant difference in the quality and longevity of the job. Built from heat-treated 8620 steel, these gears are engineered to withstand the demands of towing, off-roading, and heavy-duty applications while offering smooth, quiet operation. Revolution Gear & Axle is known for its strict manufacturing standards, ensuring that each gear set delivers long-lasting durability and precision. Plus, with an industry-leading 2-year warranty, you can install with confidence knowing your investment is protected.
