Ford 9in Ring and Pinion Lightened 620 Ratio

The Ford 9-inch Ring and Pinion Lightened 6.20 Ratio is designed for automotive builders and enthusiasts seeking enhanced performance and reliability in their rear differential setup. This gear set is essential for anyone upgrading a classic muscle car, street rod, or high-performance daily driver that may see occasional track use.

With a 6.20 gear ratio, the ring gear turns 6.20 times for each revolution of the pinion, providing a balance between quick acceleration and highway efficiency. The lightened construction minimizes unsprung mass and rotational inertia, improving throttle response and weight transfer during acceleration. These gears are precision cut and heat-treated for durability, ensuring they can withstand the stresses of daily driving and occasional hard acceleration.

Ideal for vehicles producing between 400 and 550 horsepower, whether naturally aspirated or with mild boost, this gear set is compatible with standard Ford 9-inch carriers. While it is designed to fit most applications, professional setup is recommended to ensure optimal performance and compatibility with your specific vehicle setup.
