Spec Clutch SD843H Stage 2 Plus Performance Clutch Kit

The SPEC SD843H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can handle, while still preserving the street-friendly feel and drivability that Stage 2 is known for. Bridging the gap between the SPEC Stage 2 and Stage 3 clutch kits, the Stage 2 Plus delivers drivability and engagement quality characteristic of the Stage 2, but with a 15 to 20 percent higher torque capacity.

The kit features a multi-friction disc in a full-faced configuration with carbon semi-metallic material on one side and Kevlar® on the other. Hubs are double-sprung with spring cover reliefs for flexibility, and heat-treated components for added strength and durability.

Kit Includes:

• High-clamp pressure plate
• Hybrid carbon-graphite and Kevlar® friction disc
• High-torque sprung hub and disc assembly
• Bearing and tool kit

Recommended Driving Applications:

• Street
• Drag Racing
• Road Racing
• Rally
• Pulling
• Autocross

The SPEC Stage 2 Plus is the ideal upgrade for performance-built engines that have outgrown a stock or Stage 2 clutch, delivering excellent wear characteristics and reliable daily drivability without sacrificing the higher torque threshold needed for aggressive driving.
