Spec Clutch SN543H Stage 2+ Clutch Kit with Carbon-Kevlar Multi-Friction Disc

The SPEC SN543H Stage 2+ Clutch Kit is engineered for modified engines that demand more torque capacity than the standard Stage 2 can deliver. Bridging the gap between the Stage 2 and Stage 3, this kit provides a 15–20% higher torque capacity while preserving the familiar, street-friendly engagement feel of the Stage 2.

At the core of this kit is a full-faced, multi-friction composite disc featuring carbon semi-metallic material on one side and Kevlar on the other — a proven combination for aggressive performance with manageable daily drivability. The high-clamp pressure plate delivers increased clamping force to handle elevated torque loads, while the double-sprung hub with spring cover reliefs absorbs driveline shock and reduces noise, vibration, and harshness. All hub components are heat-treated for long-term strength and durability.

Kit Includes:

• High-clamp performance pressure plate
• Multi-friction carbon semi-metallic / Kevlar composite disc
• High-torque double-sprung hub and disc assembly
• Release bearing
• Alignment tool kit

Recommended Applications:

• Street performance
• Drag racing
• Road racing
• Rally
• Autocross
• Pulling

The SPEC Stage 2+ is the ideal upgrade for performance-built engines that have outgrown a stock or Stage 2 clutch but do not require the aggressive engagement of a full Stage 3. It delivers the reliability and wear characteristics needed for both track use and spirited street driving.
