Product Details

The Spec Clutch SP873H Stage 2 Plus Clutch Kit is engineered to bridge the performance gap between the Stage 2 and Stage 3 clutch systems. It delivers the smooth drivability and predictable engagement feel of the Stage 2, while offering a 15–20% increase in torque capacity — making it an ideal step-up for drivers who need more holding power without sacrificing daily street manners.

At the core of the Stage 2 Plus is a multi-friction disc in a full-faced configuration, combining carbon semi-metallic friction material on one side with Kevlar® on the other. This hybrid design optimizes both grip and wear characteristics across a wide range of driving conditions. The hub is double-sprung with spring cover reliefs for added flexibility, and all components are heat-treated for long-term strength and durability.

Key Features:

  • High-clamp performance pressure plate for increased clamping force
  • Hybrid Kevlar® and carbon-graphite friction material for optimized grip and longevity
  • Full-faced multi-friction disc configuration for consistent engagement
  • Double-sprung hub with spring cover reliefs for flexibility and smooth engagement
  • Heat-treated components for superior strength and durability
  • Includes bearing and installation tool kit

Ideal Applications:

  • Street driving
  • Drag racing
  • Autocross
  • Road racing
  • Rally
  • Pulling
  • Drift

The SP873H Stage 2 Plus clutch kit is a complete performance upgrade for drivers seeking meaningful torque gains over a stock or Stage 2 clutch, without crossing into the aggressive engagement behavior of a full Stage 3 setup. Kit includes all necessary hardware for installation.
