Revolution Gear & Axle Ford 10.25in Rear Axle 5.13 Ratio Long Ring & Pinion Set

If you're looking to change your vehicle's gearing for larger tires or heavy towing, a new ring and pinion set is a key component. This Revolution Gear & Axle set is specifically for Ford 10.25-inch rear axles and features a 5.13 ratio, which is a common choice for trucks running 37-inch or larger tires, or for those needing improved towing torque. A lower numerical ratio like 5.13 effectively makes your engine work less at highway speeds, improving drivability with bigger tires.

Revolution Gear & Axle is known for well-built drivetrain components. This set is made from strong steel and is designed for durability. The 'long' designation in the part number refers to the pinion gear's length, which is important for proper setup and meshing with the ring gear in your specific axle housing. Getting the gear pattern right during installation is crucial for longevity and quiet operation.

When installing a new ring and pinion, it's important to have the right tools and knowledge for proper setup, including backlash and gear pattern checks. Many installers also recommend replacing axle bearings and seals at the same time to ensure a fresh, leak-free installation.
