Our Racing Beat Type I Modified 13B Rear (Standard-Ungrooved) - 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. The front gear and the standard-ungrooved rear gear have the stock bearing installed. The "special grooved" rear gear includes a three-window bearing and is intended for high power output racing engines, while the standard-ungrooved rear gear is best suited for high output streetable engines. Additionally, we offer for a nominal charge the machining process that allows the Type I front stationary gear to accommodate the larger thrust washer and related components found on the 1992 and later engines.
