Spec Clutch SY873 Stage 3 Performance Clutch Kit

The Spec Clutch SY873 Stage 3 Clutch Kit is engineered for heavily modified street and high-performance race applications that demand aggressive torque capacity without sacrificing daily drivability. This kit strikes a balance between streetable engagement and serious performance, making it a top choice for drivers who push their vehicles hard across multiple driving disciplines.

At the heart of the Stage 3 kit is a high-clamp pressure plate paired with a carbon semi-metallic puck disc — available in 4-puck or 6-puck configurations depending on the application (6-puck is standard). The sprung hub design features a double-sprung construction with spring cover relieves for flexibility, along with heat-treated components for long-term strength and durability.

What's Included:

• High-clamp performance pressure plate
• Carbon semi-metallic 4 or 6-puck sprung hub disc assembly (application dependent)
• Release bearing
• Installation tool kit

Key Features:

• Carbon semi-metallic friction material for outstanding drivability, wear life, and torque capacity
• Double-sprung hub with spring cover relieves for smooth, flexible engagement
• Heat-treated internal components for enhanced strength under high stress
• High-clamp pressure plate for increased clamping force on modified engines
• Designed and hand-built in the U.S.A.
• SFI approved

Intended Use: Street, Drag Racing, Drift, Road Race, Rallye, Pulling, Autocross

The Spec Stage 3 kit sits within SPEC's streetable performance lineup (Stages 1–3+) and is the ideal upgrade for drivers who need a clutch that can handle serious power while remaining functional for daily commuting. Existing flywheels should be resurfaced prior to installation unless a new SPEC flywheel is being used.
