Spec Clutch SB813H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SB813H 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, this kit provides 15–20% higher torque capacity while maintaining the smooth, street-friendly engagement feel that Stage 2 is known for — making it an ideal choice for high-performance builds that still see regular daily driving.

The Stage 2 Plus features a full-faced, multi-friction disc combining carbon semi-metallic material on one side and Kevlar® on the other for an optimized balance of grip, wear resistance, and engagement quality. 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.

Kit Includes:

• High-clamp performance pressure plate
• Composite multi-friction carbon/Kevlar clutch disc
• High-torque sprung hub and disc assembly
• Release bearing
• Alignment tool

Recommended Driving Applications:

• Street / Daily Driving
• Drag Racing

All Spec clutch kits are designed, hand-built, and tested in the U.S.A., delivering the precision and reliability that performance and racing drivers demand.
