Product Details

The Yukon Gear & Axle YG F9-633 ring and pinion gear set is built with high-grade steel and features a 6.33 ratio, designed to handle increased horsepower and larger tires. Yukon engineers focus on the gear tooth surface finish, aiming to reduce friction and heat buildup, which is crucial for high-torque conditions and extended use. This set is specifically designed to fit the Ford 9-inch rear axle, a popular choice for many classic and performance vehicles.

This gear set is a solid option for those looking to re-gear their Ford 9-inch differential. The 6.33 ratio offers a significant increase in torque multiplication compared to stock gearing, making it ideal for applications where improved acceleration is a priority, especially when paired with larger tires or a more powerful engine. Yukon uses advanced heat-treating techniques and rigorous testing to ensure their gears meet exacting specifications, providing a well-built component for your drivetrain.

Included with this set is Yukon's Y.E.S. Plan, a lifetime protection plan that covers your gears for as long as you own the vehicle, offering peace of mind for this significant drivetrain upgrade. While this set is designed for a direct fit in Ford 9-inch rears, professional installation is recommended to ensure proper setup and backlash for optimal performance and longevity.
