Ultimate F250 Front and Rear Gear Package with 5.38 Ratio

A proper gear ratio can make all the difference, especially when you’re running oversized tires or towing heavy loads. The Revolution Front & Rear 5.38 Koyo Bearing Ring and Pinion Gear Package is built to give your 2017-2022 F-250 the torque and performance it needs to handle any challenge. Whether you're off-roading, pulling a loaded trailer, or just looking for better power delivery, this gear package is a serious upgrade over stock. With a 5.38 gear ratio, you’ll notice an immediate improvement in throttle response, acceleration, and low-speed control. This ratio is perfect for trucks with larger-than-stock tires, helping restore lost power by bringing the engine’s RPMs back into the optimal range. Compared to longer gears like 4.10s or 4.30s, these 5.38s deliver more torque at the wheels, making it easier to get moving with heavy loads or crawl over rugged terrain. At highway speeds, the right gear ratio also prevents excessive strain on your engine, improving efficiency and drivability.

Durable Construction with Straightforward Install

Durability is key with a ring and pinion upgrade, and Revolution Gear & Axle sets the standard with premium 8620 steel construction. These gears are precision-machined and heat-treated for exceptional strength, ensuring they stand up to extreme use without premature wear. To complete the package, this kit includes a full Koyo Master Install Kit, featuring industry-leading Koyo bearings for smooth, long-lasting performance. The kit also comes with everything needed for a successful installation, including pinion seals, shims, ring gear bolts, and marking compound to set up the gears with precision.
