Description

The R154 reinforced gear set is a high-performance upgrade solution designed to withstand high RPM and high torque output. This complete set includes the main shaft, input shaft, and 1st to 5th gears. All gears are manufactured from SAE 8620 or SAE 4320H carburized alloy steel, with a carburized and quenched surface treatment that achieves a hardness of HRC 58–62, significantly enhancing wear and impact resistance. Featuring precision-cut helical gear teeth and high-accuracy hobbing and grinding processes, the gear set delivers smoother power transmission while reducing noise and energy loss. It is especially suitable for modified applications that demand long-term durability under heavy loads and reinforced drivetrain structures. With an optimized design that balances strength, longevity, and installation compatibility, this gear set is the ideal choice for enhancing both the durability and performance of your transmission system.
