Description

Motive Gear Performance ring and pinions are perfect for dedicated racing or off-road vehicles. Their gear sets are made from first-run steel, they never use recycled metal. This allows Motive Gear Performance ring and pinions to handle the extreme torque from high-horsepower racing engines. Extensive engineering, computer-controlled heat treatment, superior strength, quality and the widest selection of racing gear ratios, makes Motive Gear Performance ring and pinions the clear winner! Engineered to the highest standards, every Motive Gear Performance product goes through rigid quality control processes in their in-house lab.

Motive Gear Performance also offers a lightweight alternative to standard ring and pinion gear sets. Their 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. Motive Gear Performance: What the pros run!
