Spec Clutch SA303F-3 Stage 3+ Clutch Kit Carbon Semi-Metallic

The SPEC SA303F-3 Stage 3+ Clutch Kit is the flagship performance clutch solution for high-powered street and race vehicles that demand both maximum torque capacity and a manageable, driver-friendly engagement feel. Built around a carbon semi-metallic full-face friction disc, the Stage 3+ delivers an exceptional combination of longevity, friction coefficient stability, and real-world drivability that sets it apart from conventional performance clutch materials.

The disc assembly features a double-sprung hub with spring cover reliefs for added flexibility and smoother power transfer, while heat-treated internal components provide the strength and durability needed to withstand repeated high-load engagements. The high-clamp pressure plate ensures consistent clamping force to handle elevated torque levels without slip.

Key Features:

• Carbon semi-metallic full-face friction material — superior wear life, friction coefficient, and drivability
• High-clamp performance pressure plate — maximizes torque holding capacity
• Double-sprung hub with spring cover reliefs — flexibility and smooth engagement
• Heat-treated hub components — enhanced strength and long-term durability
• Includes bearing and installation tool kit — everything needed for installation

Ideal Applications:

• High-powered street and strip builds
