6.66 Ratio 9in Ford AX

The 6.66 Ratio 9in Ford AX ring and pinion kit from MOTIVE GEAR is specifically engineered for Ford 9-inch differentials, providing precise gear reduction that enhances torque multiplication and acceleration. This kit is ideal for street performance and drag racing, where aggressive gearing can significantly improve launch characteristics and overall driveline responsiveness.

Featuring a 28-spline pinion shaft design, the AX series component offers robust load-carrying capability and reliable engagement with the ring gear. The precision-cut gear teeth are optimized for minimal backlash and maximum efficiency, which helps reduce noise and vibration while maximizing power transfer from the driveshaft to the wheels. This ensures durability under sustained high-load conditions, making it suitable for modified engines and aggressive driving scenarios.

Enthusiasts upgrading their Ford 9-inch differentials will find significant benefits in acceleration and pulling power with this 6.66:1 gear set. It is particularly advantageous for classic muscle cars and modern hot rods, where performance improvements over stock configurations are desired. The complete kit includes both ring and pinion gears, simplifying installation and ensuring optimal gear pairing from the factory.
