Spec Clutch SV873H Stage 2+ Performance Clutch Kit

The Spec Clutch SV873H Stage 2+ Clutch Kit bridges the gap between the Stage 2 and Stage 3, delivering a 15–20% higher torque capacity while retaining the smooth, street-friendly engagement feel of the Stage 2. Rated to handle up to 456 ft-lbs of torque, this kit is an ideal upgrade for moderately modified naturally aspirated engines and power-adder builds that have outgrown the standard Stage 2's capabilities.

Friction Material & Disc Design:

• Multi-friction disc in a full-faced configuration with carbon semi-metallic on one side and Kevlar on the other
• Hybrid friction material optimizes both torque capacity and wear characteristics
• Full-faced design promotes smooth, progressive engagement

Pressure Plate & Hub Assembly:

• High-clamp pressure plate for maximum clamping force and slip resistance
• Double-sprung hub with spring cover relieves for drivetrain flex and vibration damping
• Heat-treated hub components for long-term strength and durability

Kit Includes:

• High-clamp pressure plate
• Hybrid Kevlar and carbon-graphite friction disc with high-torque sprung hub assembly
• Bearing and installation tool kit

Recommended Driving Applications:

• Street, Drag, Road Race, Rally, Pulling, Autocross, and Drift

Important Notes: This kit is designed for use with a Spec billet single-mass flywheel and requires conversion from the original dual-mass flywheel design. A new break-in period of at least 450 miles of primarily city and stop-and-go driving is required before full-throttle engagement or hard launches. Flywheel resurfacing is required if not using a new Spec flywheel.
