Spec Clutch SK203H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SK203H Stage 2 Plus Clutch Kit is engineered for drivers who need more than a Stage 2 can deliver without sacrificing the street-friendly engagement that makes daily driving practical. This performance clutch kit bridges the gap between the Stage 2 and Stage 3, delivering 15–20% greater torque capacity while retaining the smooth, predictable engagement characteristics SPEC is known for at the Stage 2 level.

At the heart of the SK203H is a multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side with Kevlar® on the other. This hybrid friction pairing optimizes grip and heat resistance across a wide range of driving conditions, from daily street commutes to competitive motorsport events.

The disc hub is double-sprung with spring cover reliefs to maximize rotational flexibility and reduce driveline shock, while heat-treated internal components ensure long-term strength and durability under sustained high-load use.

Key Features:

• Multi-friction full-faced disc with carbon semi-metallic and Kevlar® hybrid lining
• High-clamp pressure plate for increased torque holding capacity
• Double-sprung hub with spring cover reliefs for smooth power delivery and flexibility
• Heat-treated components for enhanced strength and durability
• Bearing and installation tool kit included
