Spec Clutch SK205 Stage 5 Performance Clutch Kit - Sintered Iron Full Face

The Spec Clutch SK205 Stage 5 Clutch Kit is built for drivers who demand maximum performance from their drivetrain. Featuring a full-face sintered iron disc with the highest achievable friction coefficient in the SPEC lineup, this kit delivers uncompromising torque transfer for extreme street and competition use. While technically street-drivable, the Stage 5 is engineered with the race track in mind — not the daily commute.

The disc assembly uses a solid 12-rivet unsprung hub that is heat-treated for exceptional strength and long-term durability under repeated high-stress engagements. Paired with a high-clamp pressure plate, the SK205 provides aggressive clamping force to handle serious power output without slipping.

Key Features:

• Full-face sintered iron friction disc with maximum friction coefficient
• High-clamp performance pressure plate
• Solid 12-rivet unsprung hub — heat-treated for strength and durability
• Full-metallic friction material for consistent, repeatable performance
