Product Details

If you're looking to optimize your Ford 9-inch differential for more power or larger tires, this Yukon Gear & Axle high-performance ring and pinion gear set is a solid option. It features a 4.11 ratio, which is a popular choice for balancing acceleration and highway cruising speeds, especially when you've upgraded your vehicle's horsepower or tire size. Yukon engineers focus on creating gear sets that meet strict quality standards, using high-grade steel for both the ring and pinion components. The gear tooth surface finish is designed to reduce friction and heat buildup, which is important for longevity under demanding conditions.

This set is built to fit Ford 9-inch differentials, a robust axle commonly found in a wide range of Ford vehicles from the 1950s through the 1980s, including models like the Ford Bronco, F-100, and Mustang. The 4.11 ratio offers a noticeable improvement in acceleration compared to stock gearing, making it a great choice for drivers who want a more responsive feel from their vehicle. Yukon also backs these gear sets with a 1-year warranty against manufacturing defects, and they offer an optional lifetime Y.E.S. Plan for comprehensive protection.
