  6. Detailed Product Description

  The (NEW) HKS Sequential Transmission – Mazda RX-7 FD3S was developed for enthusiasts who demand more than a conventional manual gearbox can offer. Sequential transmissions are widely used in professional motorsport because they provide faster, more consistent gear changes while minimizing the risk of missed shifts during hard driving.

  Unlike traditional H-pattern transmissions that require navigating multiple gear gates, a sequential gearbox allows the driver to move directly through the gears in sequence. This creates a more intuitive and performance-focused driving experience, particularly during track sessions, time attack events, circuit racing, and high-performance street use.

  Product Specifications

  Designed for Serious Performance

  The FD3S RX-7 is known worldwide as one of the greatest rotary-powered sports cars ever produced. As power levels increase, the factory transmission can become a limiting factor in competitive environments. HKS engineered this sequential transmission to provide faster gear engagement and greater drivetrain confidence under demanding conditions.

  The result is improved performance consistency, particularly during:

  • Circuit racing
  • Time attack competition
  • Drag racing
  • Drift builds
  • High-power street applications
  • Professional motorsport projects

  Installation Considerations

  As a motorsport-oriented component, installation should be performed by an experienced technician familiar with RX-7 drivetrains and performance transmissions. Proper setup helps ensure optimal operation, longevity, and performance.

  Because this transmission is designed specifically for performance use, buyers should verify compatibility with their existing drivetrain components, engine setup, and intended application.

  Included OS Giken Triple Plate Clutch

  Adding further value to this package is the included OS Giken triple plate clutch, a highly respected performance clutch system known for handling significant torque loads while maintaining dependable engagement characteristics.

  The combination of a genuine HKS sequential gearbox and OS Giken clutch creates a drivetrain package capable of supporting ambitious rotary performance goals.
