Product Details

If you're looking to re-gear your Ford 9-inch differential, perhaps to handle larger tires or a bit more horsepower, this Yukon Gear & Axle high-performance ring and pinion set is a solid option. This set features a 4.56 ratio, which is a popular choice for balancing highway drivability with improved acceleration and towing capability, especially when paired with larger tires. It's designed to fit the robust Ford 9-inch axle housing, a common setup in many classic Ford trucks and performance vehicles.

Yukon engineers focus on creating gear sets that can handle demanding conditions. They use high-grade steel for both the ring and pinion gears, and the tooth surface finish is designed to reduce friction and heat buildup. This attention to detail helps ensure longevity, even when you're putting down serious power or covering long distances. The fitment is designed to OEM specifications, meaning it should integrate smoothly into your existing Ford 9-inch differential housing.

This gear set is backed by Yukon's commitment to quality, including a 1-year warranty against manufacturing defects. For even greater peace of mind, they also offer an optional Y.E.S. Plan for lifetime protection. This set is a great choice for owners of vehicles like the Ford Bronco, F-100, or Mustang looking to fine-tune their drivetrain's performance.
