Our Race Series ProGear 21 is the most advanced, high-tech gear oil available today and challenges traditional and other synthetic gear oils, which must be thick to handle high loads. Ultra High Film Strength and Advanced Extreme Pressure additives reduce friction, hydrodynamic drag, and gear box temperatures while offering superior hot and cold temperature performance. ProGear 21 is ideal for use with high performance cars, motorcycle, and marine gear systems.
