Spec Clutch SF373 Stage 3 Clutch Kit - Street, Drag, Drift & Race

The SPEC SF373 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand superior holding power without sacrificing everyday drivability. Designed for drivers who push their vehicles hard across a wide range of performance applications, the Stage 3 delivers confident engagement and a comfortable pedal feel that remains manageable even in daily driving conditions.

At the core of this kit is a high-clamp pressure plate paired with a 4 or 6 puck carbon semi-metallic friction disc featuring a high-torque sprung hub assembly. The sprung hub design helps absorb drivetrain shock and reduces chatter, extending the life of the clutch and surrounding components. The 6 puck configuration is standard on most applications, with the 4 puck available as a specified option at time of ordering. The kit also includes a release bearing and installation tool kit for a complete, ready-to-install package.

Key Features:

• High-clamp pressure plate for increased torque capacity
• Carbon semi-metallic friction material for durability under high heat and stress
• 4 or 6 puck disc configuration (6 puck standard; 4 puck available by request)
• High-torque sprung hub disc assembly for smoother engagement and reduced drivetrain shock
• Includes release bearing and installation tool kit
• Good wear characteristics under both low and high stress conditions

Intended Driving Applications: Street, Drag Racing, Drift, Road Racing, Rallye, Pulling, Autocross

The SPEC Stage 3 is the ideal upgrade for performance enthusiasts who need a clutch that can handle serious power levels while still functioning reliably on the street.
