Spec Clutch SC074-3 Stage 4 Clutch Kit - 6-Puck Carbon-Graphite

The Spec Clutch SC074-3 Stage 4 Clutch Kit is a high-performance, race-oriented clutch system built for drivers who demand maximum torque capacity and durability. As a solid hub evolution of the Stage 3, this kit features a solid 8-rivet hub with a fully heat-treated disc assembly engineered for exceptional strength under extreme load.

The SC074-3 is the 6-puck configuration, offering the smoothest engagement of the Stage 4 puck options — making it the most manageable choice for aggressive street and track use. While technically street-drivable, the rigid solid hub design means this kit is best suited for performance and competition driving rather than daily commuting.

Key Features:

• Solid 8-rivet hub — heat-treated for maximum strength and durability
• High-clamp pressure plate for superior clamping force under power
• Carbon-graphite friction material for high torque capacity and fade resistance
• 6-puck disc configuration — smoothest engagement in the Stage 4 lineup
• High-torque solid hub and disc assembly
• Bearing and tool kit included

Ideal Driving Applications:

• Drag Racing
• Road Racing
• Rally / Rallycross
• Drifting
• Pulling
• Autocross

For comparison: the 3-puck variant offers the lightest rotating mass, while the 4-puck strikes a balance between weight and drivability. The 6-puck (this kit) delivers the smoothest pedal feel of the three Stage 4 configurations. All Stage 4 kits step up significantly from the Stage 3 by replacing the sprung hub with a solid hub design, maximizing torque handling at the cost of street comfort.
