Spec Clutch SC173H Stage 2+ Performance Clutch Kit

The SPEC SC173H Stage 2+ Clutch Kit bridges the gap between the Stage 2 and Stage 3 lineups, delivering enhanced torque capacity without sacrificing the street-friendly drivability that defines the Stage 2. It 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 resists heat and wear under demanding conditions.

Compared to the standard Stage 2, the Stage 2+ delivers a 15–20% higher torque capacity, making it an ideal upgrade for performance builds that need more holding power while maintaining smooth engagement. The hub is double sprung with spring cover reliefs, providing torsional flexibility and reducing drivetrain shock, while heat-treated components ensure long-term strength and durability.

Key Features:

• Multi-friction disc — full-faced design with carbon semi-metallic on one side and Kevlar on the other
• High-clamp pressure plate for increased clamping force and torque capacity
• 15–20% higher torque capacity over the standard Stage 2
• Double-sprung hub with spring cover reliefs for flexibility and drivetrain protection
• Heat-treated components for enhanced strength and longevity

The SPEC Stage 2+ is engineered for drivers who demand more than a stock replacement clutch can offer, delivering a performance-focused upgrade that remains comfortable for daily or mixed-use driving.
