Spec Clutch ST853H Stage 2 Plus High-Performance Clutch Kit

The Spec Clutch ST853H Stage 2 Plus Clutch Kit bridges the gap between the standard Stage 2 and Stage 3 clutch systems, delivering the smooth daily-drivability of the Stage 2 with a 15–20% higher torque capacity. It is purpose-built for modified engines that have exceeded the torque threshold of the standard Stage 2 kit, making it an ideal upgrade for high-performance street cars that also see track time.

At the heart of this kit is a full-faced multi-friction disc that pairs carbon semi-metallic material on one side with Kevlar® on the other. This hybrid friction surface delivers consistent engagement, excellent wear characteristics, and the grip needed to handle elevated torque demands without sacrificing pedal feel.

Key Features:

• High-clamp pressure plate for increased clamping force over stock
• Hybrid carbon-graphite and Kevlar® friction material in a full-faced disc configuration
• Double-sprung hub with spring cover reliefs for flexibility and smooth engagement
• Heat-treated hub components for enhanced strength and long-term durability
• High-torque sprung hub and disc assembly engineered for modified drivetrains
• Bearing and alignment tool kit included for straightforward installation

Ideal Driving Applications: Street, Drag Racing, Road Racing, Rally, Autocross, Pulling, and Drift

All Spec Clutch products are designed, hand-built, and tested in the USA. The Stage 2 Plus is recommended for highly modified, primarily street-driven vehicles that will also see occasional track use. Note: Compatible with Spec Clutch flywheels; flywheel sold separately.
