Spec Clutch SY915 Stage 5 Clutch Kit - Full Metallic Sintered Iron Disc

The SPEC SY915 Stage 5 Clutch Kit is SPEC's most aggressive single-disc clutch offering, engineered for heavily modified drag race and pulling applications that demand the absolute highest torque capacity. Featuring a full-metallic sintered iron friction disc with the highest available friction coefficient in the SPEC lineup, this kit is purpose-built for competition use where maximum clamping force and torque transfer are the top priority.

Key Features:

• Full-metallic sintered iron disc — highest possible friction coefficient for maximum torque transfer
• High-clamp pressure plate — delivers extreme clamping loads beyond standard performance clutches
• Solid 12-rivet unsprung hub assembly — heat-treated for superior strength and durability under high-stress conditions
• Full-faced disc configuration — optimized for consistent engagement under race conditions
• Bearing and tool kit included — everything needed for a complete installation

Important Notes:

• Not street-friendly — the unsprung solid hub does not absorb drivetrain vibrations, resulting in harsh engagement and clutch chatter under normal driving conditions
• Best suited for drag racing and pulling applications with heavily modified engines
• Custom configuration may be recommended — contact a SPEC technical representative with details about your specific build and intended use before ordering

SPEC clutch components are manufactured on-site using advanced production methods and strict tolerances, making the Stage 5 kit a trusted choice for serious competition builds requiring uncompromising performance.
