Revolution Gear & Axle 97-19 Ford F-150 9.75in Rear Axle 4.10 Ratio Ring & Pinion Set

What you get with this Revolution Gear & Axle kit is a new ring and pinion gear set, specifically designed with a 4.10 gear ratio for the 9.75-inch rear axle found in 1997 through 2019 Ford F-150 trucks. This set is what you'll need if you're looking to change your truck's final drive ratio, which can be beneficial for a few reasons. A 4.10 ratio is a popular choice for F-150 owners who have added larger tires or are towing frequently, as it helps bring your engine's RPMs back into a more efficient range at cruising speeds, improving acceleration and reducing strain on the drivetrain.

Revolution Gear & Axle is known for making well-built drivetrain components, and this ring and pinion set is no exception. They are manufactured to meet strict tolerances, ensuring a proper mesh between the ring and pinion gears. This is crucial for smooth operation, reduced noise, and long-term durability. When installing a new ring and pinion, proper setup, including backlash and pattern checking, is essential for optimal performance and longevity, so be sure to follow the manufacturer's installation guidelines or have a qualified mechanic perform the work.
