Motive Gear is a manufacturing industry leader in professional quality, high performance ring and pinion sets. The superior quality of these gear sets is the result of years of racing development, outstanding design, and state-of-the-art manufacturing methods. Motive Gear performance products can often be found in the winner's circle at NHRA, IHRA, ANDRA, SODA, SCORE, and NASCAR events. Motive Gear ring and pinion sets are available in a wide range of ratios for most applications. Motive Gear also offers a lightweight alternative to standard ring and pinion gear sets. The new AX series ring and pinions are designed to increase horsepower and efficiency by removing rotating weight. Professional race teams have used custom-lightened drivetrain parts for years, resulting in faster times and more wins. The AX series gears from Motive are lightened during the manufacturing process; this results in gear sets that have been engineered, not modified. Computer-controlled heat treatment, index tooth spacing, and CNC machining all go into AX series performance gear sets.
