Our Racing Beat Type I Modified 13B Rear (Special-Grooved) Stationary Gears are strongly recommended for engines which are regularly running near or above 8,500 RPM. These gears have had several machining modifications performed, as well as heat-treating of the teeth to improve fatigue resistance and yield strength.
