Product Details

The SPEC SF423H Stage 2 Plus Clutch Kit bridges the gap between the Stage 2 and Stage 3 performance levels, delivering a versatile solution for drivers who demand both street manners and elevated torque capacity. The kit features a multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side with Kevlar on the other for a hybrid friction surface that balances engagement feel with durability.

Compared to the standard Stage 2, the Stage 2 Plus delivers a 15–20% higher torque capacity while retaining the smooth drivability and progressive engagement quality that makes the Stage 2 a popular street choice. The hub is double sprung with spring cover reliefs for added flexibility, and all hub components are heat treated for long-term strength and durability under demanding conditions.

Key Features:

  • Hybrid friction disc — Carbon semi-metallic on one side, Kevlar on the other, in a full-faced configuration
  • High-clamp pressure plate for increased torque holding capacity
  • Double-sprung hub with spring cover reliefs for flexibility and smooth power transfer
  • Heat-treated hub components for improved strength and longevity
  • 15–20% higher torque capacity over the standard Stage 2
  • Includes bearing and installation tool kit for a complete installation

Intended Use:

  • Street
  • Drag Racing
  • Pulling
  • Autocross
  • Road Racing
  • Rallye
  • Drift

The SPEC SF423H Stage 2 Plus is an ideal upgrade for performance enthusiasts who need more torque capacity than a stock or Stage 2 clutch can provide, without sacrificing the daily-driving comfort of a full-faced friction disc.
