Spec Clutch SZ943H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SZ943H Stage 2 Plus Clutch Kit is engineered for modified engines that have outgrown the torque capacity of a standard Stage 2 clutch. Bridging the gap between the Stage 2 and Stage 3, this kit delivers the smooth engagement and daily drivability feel of the Stage 2 while providing a 15–20% higher torque capacity — making it an ideal step-up for street-driven performance builds.

The disc uses a full-face, multi-friction configuration with carbon semi-metallic material on one side and Kevlar on the other, combining excellent wear characteristics with strong grip and heat resistance. 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:

• High-clamp pressure plate for increased clamping force
• Hybrid carbon-graphite and Kevlar friction disc in a full-face configuration
• Double-sprung hub with spring cover reliefs for flexibility and smooth engagement
• Heat-treated hub components for strength and durability
• High-torque sprung hub and disc assembly
• Includes release bearing and installation tool kit

Intended Use: Street, Drag, Road Race, Rally, Autocross, Pulling, Drift

All Spec Clutch products are designed, hand-built, and tested in the USA to strict tolerances, ensuring consistent performance whether you're daily driving or pushing hard on the track.
