Product Details

If you're looking to change your differential gearing, perhaps to better handle larger tires or a significant increase in horsepower, a high-performance ring and pinion set is a key component. This Yukon Gear & Axle set is designed for Ford 10.5-inch rear differentials, offering a 4.30 ratio. This ratio is a popular choice for trucks and SUVs that have been upgraded with larger tires, helping to bring the engine's RPM back into its optimal power band for better acceleration and towing performance.

Yukon engineers focus on creating durable gears that can handle demanding use. They use high-grade steel for both the ring and pinion, and the tooth surface finish is designed to reduce friction and heat buildup. This is important for longevity, especially when you're pushing your vehicle with added power or larger tires. The fitment is designed to OEM specifications, meaning it should integrate smoothly into your existing differential housing. This particular set features a 31-spline pinion and requires 12 ring gear bolts for installation.

This Yukon Gear & Axle set is a solid option for a wide range of Ford trucks and SUVs from the late 90s through 2010, including models like the F-150, F-250 Super Duty, and Ford Excursion. It's backed by Yukon's commitment to quality, including a 1-year warranty against manufacturing defects, and they also offer an optional Y.E.S. Plan for lifetime coverage. Keep in mind that changing your gear ratio typically requires professional installation and may involve additional components like master bearing kits.
