3.50 Ford 9in Pro Gear 35 Spline

The 3.50 Ford 9in Pro Gear 35 Spline from RICHMOND is a precision-engineered ring and pinion set designed for serious Ford 9-inch differential builders and hot rod enthusiasts. This gear ratio component is essential for custom vehicle builds where performance, durability, and reliability under high-stress conditions are critical. Whether you're constructing a street rod, off-road rig, or high-horsepower muscle car, the Pro Gear lineup delivers the quality and consistency that separates professional builds from amateur installations.

The 3.50 ratio designation refers to the gear reduction—for every 3.50 turns of the ring gear, the axles complete one full rotation—making this ratio ideal for performance applications. The 35-spline design indicates the number of teeth engagement points on the axle splines, providing superior load distribution and strength compared to lower-spline counts. RICHMOND Pro Gear sets are manufactured using premium materials and tight tolerances, ensuring smooth mesh patterns, reduced noise, minimal backlash, and extended service life even in competition or severe-duty applications.

Builders working with stock or slightly modified Ford 9-inch differentials will find this gear set beneficial for enhancing performance. It is particularly suited for applications where a balance of acceleration and efficiency is desired, making it a great choice for custom builds. However, it is important to consider the specific driving conditions and vehicle requirements to ensure optimal performance.
