9310 Steel
High impact resistance for track use
Durable
Rolled splines increase tooth strength
Precision made
Made in the USA

核心功能

  • Computer Numerical Controlled (CNC) cut teeth which improves gear meshing, reduces stress, and ensures smooth engagement.
  • Rolled splines for additional tooth strength and longer life.
  • Computer controlled heat-treated steel for exceptional durability.  

Super Finish

An isotropic precision finish is available on both street and competition models. By reducing friction and wear, it provides 3-5% more horsepower, improves oil retention, and eliminates the break-in period.
