Spec Clutch SU073 Stage 3 Clutch Kit

The SPEC Stage 3 Clutch Kit (SU073) is engineered for heavily modified street and race applications, delivering the aggressive clamping force needed to handle elevated power levels while maintaining acceptable daily drivability. The Stage 3 offers a firm but manageable pedal feel with quick, positive engagement — making it a popular choice for builds that see both street miles and track duty.

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. The sprung hub design helps absorb drivetrain shock and reduces chatter at low speeds. The 6-puck disc configuration is standard on most applications, though a 4-puck disc can be specified at the time of ordering for slightly different engagement characteristics.

Key Features:

• High-clamp pressure plate for increased torque capacity
• Carbon semi-metallic 4 or 6 puck friction disc (6-puck standard)
• High-torque sprung hub and disc assembly
• Good wear characteristics under both low and high-stress conditions
• Comfortable pedal feel with quick engagement
• Kit includes pressure plate, disc, release bearing, and installation tool kit

Ideal Driving Applications:

• Street / Daily Driving
• Drag Racing
• Drifting
• Road Racing
• Rallye
• Pulling
• Autocross

The SPEC Stage 3 strikes the balance between race-ready performance and everyday usability, making it one of the most versatile options in the SPEC performance clutch lineup for modified vehicles.
