8.8" 3.27 Ring Gear and Pinion

The Ford Performance 8.8" 3.27 Ring Gear and Pinion set is engineered to provide superior strength and quiet operation for your Mustang's rear axle. Manufactured in the USA at Ford's Sterling Axle Plant, these gears boast OEM quality with enhanced surface finish and hardening processes, making them the strongest and quietest available in their class. This gear set is designed for an 8.8-inch axle diameter and features a 3.27 gear ratio, offering an upgrade from stock specifications for improved performance. The forged construction and CNC-cut, lapped gear teeth ensure durability for street or track use. The black oxide finish provides corrosion resistance. When changing your rear axle gear ratio, it's important to recalibrate your Mustang's speedometer. A Ford Racing Speedometer Recalibration Tool is recommended to correct this. Additionally, a master bearing installation kit is advised by most installers, particularly for high-mileage vehicles, to ensure proper setup and longevity. Ford Performance offers various installation kits designed for all 8.8-inch axles from 1986-present. This Ford Racing Ring and Pinion Gear set is specifically designed to fit all 1999 to 2004 4.6L V8 Mustangs, including the GT, Bullitt, and Mach 1 models.
