Spec Clutch SA064 Stage 4 Clutch Kit

The SPEC SA064 Stage 4 Clutch Kit is engineered for heavily modified, high-output engines where maximum torque capacity, instantaneous engagement, and reduced rotating mass are critical. This is a competition-grade clutch intended for dedicated performance and racing applications — not recommended for daily street driving due to its aggressive, near-instant engagement characteristics.

Key Features:

• Solid hub design — a rigid, 8-rivet heat-treated hub assembly delivers maximum power transfer with zero flex under extreme load
• High clamp pressure plate — significantly increased clamping force over OEM and street-performance stages for reliable hold at high torque levels
• Carbon semi-metallic friction disc — available in 3, 4, or 6-puck configurations to suit specific power levels and engagement preferences
• Lightweight construction — reduced rotational mass improves throttle response and rev characteristics
• Complete kit — includes pressure plate, clutch disc, release bearing, alignment tool, and carrier assembly hardware

Recommended Driving Applications:

• Drag Racing
• Drifting
• Road Racing
• Rallye
• Pulling
• Circle Track

The SPEC Stage 4 is the solid-hub evolution of the Stage 3 clutch, delivering maximum grip and durability for competition builds that demand uncompromising performance.
