Spec Clutch SD853H-2 Stage 2 Plus Performance Clutch Kit

The Spec Clutch SD853H-2 Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can handle. Bridging the gap between the Stage 2 and Stage 3, the Stage 2 Plus delivers the same smooth, street-friendly engagement feel of the Stage 2 while offering a 15–20% higher torque capacity — making it an ideal upgrade for high-performance builds that still see regular street use.

At the core of this kit is a multi-friction disc in a full-face configuration, combining carbon semi-metallic material on one side and Kevlar® on the other for exceptional wear resistance and consistent bite. The double-sprung hub features spring cover reliefs for added flexibility, while heat-treated internal components provide long-term strength and durability under demanding conditions.

Key Features:

• High-clamp pressure plate for increased torque holding capacity
• Composite multi-friction disc — carbon semi-metallic / Kevlar® full-face configuration
• Double-sprung hub with spring cover reliefs for smooth, flexible engagement
• Heat-treated components for enhanced strength and durability
• High-torque sprung hub and disc assembly
• Bearing and alignment tool kit included

Intended Use: Street, Drag Racing, Road Racing, Rally, Pulling, Autocross, Drifting

The SD853H-2 is an excellent choice for drivers who need elevated torque capacity without sacrificing the daily drivability and progressive engagement that SPEC's Stage 2 platform is known for.
