Spec Clutch SN443H Stage 2 Plus Clutch Kit

The SPEC SN443H 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, the Stage 2 Plus offers a 15–20% higher torque capacity while preserving the familiar engagement feel and daily drivability of the Stage 2.

The multi-friction disc uses a full-faced configuration with carbon semi-metallic material on one side and Kevlar® on the other, providing an optimal balance of grip, wear resistance, and smooth engagement. The double-sprung hub features spring cover reliefs for added flexibility, along with heat-treated components for long-term strength and durability under demanding conditions.

Key Features:

• High-clamp pressure plate for increased torque holding capacity
• Hybrid carbon semi-metallic / Kevlar® full-faced multi-friction disc
• Double-sprung hub with spring cover reliefs for smooth, flexible engagement
• Heat-treated hub components for superior strength and durability
• Includes release bearing and installation tool kit
• Designed and hand-built in the U.S.A.

Recommended Driving Applications: Street, Drag Racing, Road Racing, Rally, Autocross, Pulling, and Drifting

The SPEC Stage 2 Plus is the ideal upgrade for performance-modified vehicles that need more torque capacity without sacrificing the street-friendly feel of a Stage 2 clutch.
