Premium Gear Package for Ford Super Duty

If you're looking to maximize the performance of your 2017-2022 F-250, upgrading to the Revolution 4.88 Front & Rear Ring and Pinion Gear Package is a smart move. Whether you're running oversized tires, hauling heavy loads, or taking your truck off the beaten path, a deeper gear ratio like 4.88 helps restore power and efficiency where it matters most. This setup enhances low-end torque, improving acceleration and throttle response while reducing strain on your drivetrain. The result? Better towing capability, smoother power delivery, and a more controlled driving experience—especially when climbing steep grades or navigating challenging terrain. When compared to other ratios, 4.88 strikes a solid balance—offering more low-end grunt than a 4.30 or 4.56, while still maintaining reasonable RPMs at highway speeds. If you've upgraded to larger tires, this is the gear ratio that helps bring back the factory-like performance your truck was designed for.
