Spec Clutch SC443H-2 Stage 2 Plus Performance Clutch Kit

The Spec Clutch SC443H-2 Stage 2 Plus is a high-performance clutch kit engineered for modified engines that demand more torque capacity than a standard Stage 2 unit can deliver. Bridging the gap between the Stage 2 and Stage 3, this kit delivers 15–20% higher torque capacity while preserving the smooth engagement and daily drivability characteristics the Stage 2 is known for.

The kit features a multi-friction composite disc in a full-faced configuration, with carbon semi-metallic material on one side and Kevlar on the other — a hybrid design that balances aggressive torque handling with streetable feel and excellent wear life. The double-sprung hub includes spring cover reliefs for added flexibility, along with heat-treated components for long-term strength and durability. A high-clamp pressure plate rounds out the assembly for maximum clamping force on modified powerplants.

Kit Includes:

• High-clamp performance pressure plate
