Spec Clutch SN453H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SN453H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can handle, while still delivering the street-friendly drivability the Stage 2 is known for. Bridging the gap between the Stage 2 and Stage 3, this kit delivers a 15–20% higher torque capacity without sacrificing everyday engagement quality.

The multi-friction disc uses a full-faced configuration with carbon semi-metallic material on one side and Kevlar on the other, combining the grip and heat resistance of carbon-graphite with the smooth, long-wearing characteristics of Kevlar. The hub is double-sprung with spring cover reliefs for enhanced flexibility, and all components are heat-treated for superior strength and durability.

Key Features:

• High-clamp performance pressure plate for increased clamping force
• Hybrid carbon-graphite and Kevlar multi-friction disc in full-faced configuration
• 15–20% higher torque capacity versus Stage 2
• Double-sprung hub with spring cover reliefs for flexibility and smooth engagement
• Heat-treated components for long-term strength and durability
• Includes release bearing and installation tool kit
• Designed, hand-built, and tested in the USA

Suitable for a wide range of performance driving applications including street, drag racing, road racing, autocross, rally, pulling, and drifting. The Stage 2 Plus is an ideal upgrade for any modified engine making more torque than a Stage 2 can support, yet still requiring a livable daily-driving clutch feel.
