  • GEAR RATIOS

    We carefully research each engine and intended racing application to formulate the most suitable gear ratios to maximize the engine’s potential. The gears are intended to keep the engine operating at its peak optimal power-band thus allowing the vehicle to continue to accelerate as efficiently as possible

  • MATERIALS

    Each gear component is designed and created from high-quality forged materials, and then undergoes hard shot peening, resulting in increased strength and durability.

  • GEAR PROFILE

    Our gears are helical-cut rather than straight-cut in order to maintain a quiet operation as well as increased reliability for racing.

1st: 2.596

2nd: 1.765
