Spec Clutch SC073F-2 Stage 3 Plus Clutch Kit

The Spec SC073F-2 Stage 3 Plus Clutch Kit is the flagship performance clutch solution engineered for heavily modified street and race engines that demand torque capacity beyond what the standard Stage 3 can support. It delivers the best balance of aggressive holding power and everyday manageability in the Spec performance clutch lineup.

At the heart of the Stage 3+ is a full-faced carbon semi-metallic friction disc — a material chosen for its exceptional combination of long service life, consistent friction coefficient, and streetable engagement feel. Unlike puck-style discs, the full-face design spreads clamping load evenly across the entire friction surface, reducing heat buildup and extending component life under sustained high-torque conditions.

The disc hub is double-sprung with spring cover reliefs for added driveline flexibility, while heat-treated internal components provide the structural strength needed to withstand repeated high-load launches and aggressive driving cycles.

Kit Includes:

• High-clamp performance pressure plate
• Full-faced carbon semi-metallic friction disc with high-torque sprung hub assembly
• Release bearing
• Installation tool kit

Intended Use:

• Street (heavily modified / high-torque builds)
• Drag Racing
• Drifting
• Road Racing
• Pulling
• Rally
• Autocross

The Stage 3+ steps up from the Stage 3 with improved wear characteristics and a more manageable pedal feel, making it an ideal choice for high-powered daily-driven or dual-purpose street/track builds that require reliable clutch performance without sacrificing drivability.
