Shorter Gear Provides More Low-End Power

If you’ve upgraded to larger tires or need more low-end power for towing and off-road performance, re-gearing your truck is one of the best modifications you can make. The Revolution Gear & Axle 4.88 Ring & Pinion Gear Set is designed for the Dana 60 front axle in 2017-2022 Ford F-250, F-350, and F-450 trucks, giving you a stronger and more efficient drivetrain. When running oversized tires, factory gearing can feel sluggish, forcing the engine to work harder just to maintain speed. This 4.88 gear ratio restores lost power, improves acceleration, and helps keep your truck in its optimal RPM range, whether you're tackling steep inclines, hauling heavy loads, or just hitting the trails. The 4.88 gear ratio is ideal for truck owners who want to regain lost torque without going to an extreme. Compared to numerically lower gears like 4.30s, the 4.88 ratio provides stronger low-end response, making it easier to move heavy loads and navigate rough terrain. It also helps improve throttle response and drivability when running 35-inch or larger tires. On the other hand, higher numerical gears like 5.38s maximize low-speed power but can push RPMs higher at highway speeds, which isn’t ideal for trucks that still see daily road use. The 4.88 ratio strikes a balance, giving you the low-end power needed for towing and off-roading while still keeping RPMs reasonable for highway cruising.
