USA Standard Ring & Pinion Gear Set For Ford 9in in a 5.13 Ratio

When you're rebuilding the rear end of your Ford, especially for applications that demand more torque multiplication like towing or off-roading, changing the ring and pinion ratio is a common and effective way to tune your vehicle's performance. This USA Standard Gear set for the Ford 9-inch rear axle offers a 5.13 ratio, which is significantly lower than stock and will provide much stronger acceleration.

Yukon Gear & Axle designs these USA Standard sets to go beyond factory specifications, meaning they're built to handle more stress than original equipment. Each set undergoes strict in-house checks for dimensions, materials, and proper fitment, ensuring you get a well-built component that performs reliably. The 5.13 ratio is ideal for larger tires or when you need to get heavy loads moving quickly, giving your vehicle a noticeable boost in low-end grunt.

This ring and pinion set fits a wide range of classic Ford vehicles equipped with the 9-inch rear end, including models like the Ford Bronco (1966-1986), Ford F-100 (1957-1983), and Ford Mustang (1965-1973). Remember that changing your gear ratio may also require recalibrating your speedometer to ensure accurate readings.
