Spec Clutch SF743H Stage 2 Plus Performance Clutch Kit

The SPEC SF743H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can deliver, while still retaining the smooth, streetable engagement feel that Stage 2 is known for. Bridging the gap between the Stage 2 and Stage 3, this kit delivers 15–20% higher torque capacity without sacrificing daily drivability or clutch life.

The Stage 2 Plus features a composite multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side with Kevlar® on the other for an optimal balance of grip, heat resistance, and longevity. The hub is double-sprung with spring cover reliefs for flexibility, and all hub components are heat-treated for long-term strength and durability.

Key Features:

• High-clamp pressure plate for increased torque holding capacity
• Full-faced composite multi-friction disc — carbon semi-metallic and Kevlar® construction
• Double-sprung hub with spring cover reliefs for smooth, flexible engagement
