Spec Clutch SA313H Stage 2 Plus Performance Clutch Kit

The SPEC SA313H 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 Stage 2 and Stage 3, this kit delivers the familiar, streetable engagement feel of the Stage 2 while providing a 15–20% higher torque capacity — making it the ideal upgrade for performance-built engines without sacrificing daily drivability.

Key Features:

• Multi-friction composite disc in a full-faced configuration — carbon semi-metallic material on one side and Kevlar® on the other for exceptional grip and wear resistance
• High-clamp pressure plate for increased clamping force to handle elevated torque loads
• Double-sprung hub with spring cover reliefs for smooth, flexible engagement and reduced drivetrain shock
• Heat-treated hub components for long-term strength and durability under demanding conditions
• Complete kit includes high-torque sprung hub and disc assembly, pilot bearing, release bearing, and alignment tool

Recommended Driving Applications:

• Street / Daily Driving
• Drag Racing
• Road Racing
• Rally
• Autocross

Designed, hand-built, and tested in the U.S.A., SPEC clutches are trusted by performance and racing drivers worldwide for their strong grip, extreme holding power, and consistent reliability across all driving environments.
