Spec Clutch SD773 Stage 2 Plus Performance Clutch Kit

The Spec Clutch SD773 Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can deliver. Bridging the gap between the Stage 2 and Stage 3, the Stage 2 Plus retains the smooth, street-friendly engagement feel of the Stage 2 while providing approximately 15–20% greater torque capacity — making it an ideal upgrade for high-output builds that still see daily street use.

• Multi-friction composite disc in a full-faced configuration — carbon semi-metallic material on one side, Kevlar® on the other
• High-clamp pressure plate for increased clamping force without sacrificing modulation
• High-torque sprung hub and disc assembly for reliable power transfer and damping
• Double-sprung hub with spring cover reliefs for added flexibility and reduced driveline shock
• Heat-treated internal components for long-term strength and durability

Designed and hand-built in the USA, the Spec SD773 Stage 2 Plus delivers the performance headroom needed for modified powerplants while maintaining the engagement quality and wear characteristics expected from a premium daily-driven performance clutch.
