Improve Low-End Torque and Throttle Response with Revolution Gear

Upgrading your truck's gearing is one of the best ways to maximize performance, especially when running oversized tires or hauling heavy loads. The Revolution Front & Rear 5.38 Koyo Bearing Ring and Pinion Gear Package is designed to give your 2011-2016 F250 the torque and power delivery it needs for demanding applications. If you’ve noticed sluggish acceleration, excessive strain on your drivetrain, or a lack of pulling power with larger tires, this upgrade will get your truck back to performing at its best. A 5.38 gear ratio is ideal for those who prioritize low-end torque and need extra grunt when towing, rock crawling, or tackling steep terrain. Compared to taller gears, this setup allows your engine to stay in the optimal power band, reducing stress on your transmission and improving overall drivability. Whether you’re off-road, on the job site, or pulling heavy loads, this setup ensures that power gets to the ground efficiently.

Premium Construction & Design

Revolution Gear and Axle is known for precision craftsmanship, and this package is no exception. The ring and pinion sets are made from premium 8620 steel, heat-treated for superior strength and longevity. The included Koyo bearings are some of the best in the industry, offering smooth operation, durability, and resistance to wear under extreme conditions. This master install kit also includes all the necessary shims, seals, and hardware for a seamless installation. Better yet, installing a ring and pinion gear set requires technical knowledge, but this package is designed for a straightforward fit. It’s built specifically for Ford’s 10.5-inch rear axle and Dana 60 front axle, ensuring compatibility without unnecessary modifications. When properly installed, you’ll notice improved throttle response, better power delivery, and a more controlled driving experience—especially when towing or navigating uneven terrain.
