Spec Clutch SN053H Stage 2 Plus Clutch Kit for Modified High-Torque Engines

The SPEC SN053H Stage 2 Plus 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 smooth, familiar engagement feel of the Stage 2 — making it a strong choice for both performance driving and everyday street use.

At the core of this kit is a composite multi-friction disc in a full-faced configuration, featuring carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction material delivers excellent wear characteristics, strong torque transfer, and predictable engagement across a wide range of operating conditions.

Key Features:

• High-clamp performance pressure plate for increased clamping force
• Multi-friction carbon/Kevlar composite disc for superior wear and torque capacity
• Double-sprung hub with spring cover relieves for flexibility and heat-treated components for durability
• High-torque sprung hub and disc assembly
• Includes release bearing and installation tool kit

Intended Driving Applications:

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

All SPEC clutch components are designed, hand-built, and tested in the U.S.A., ensuring precision fitment and long-term reliability for high-performance applications.
