Spec Clutch SP842-3 Stage 2 Kevlar Clutch Kit

The Spec Clutch SP842-3 Stage 2 Clutch Kit is engineered for street performance enthusiasts and drivers with mildly to moderately modified naturally aspirated or power-adder engines. It delivers the ideal balance of stock-like daily drivability and substantially improved torque capacity — making it equally at home on a daily commute or at a weekend autocross event.

Built around a pure Kevlar friction disc with steel backing, the Stage 2 offers excellent wear characteristics and longer service life compared to the Stage 1, while retaining the smooth, predictable engagement SPEC is known for. The high-clamp pressure plate increases clamping force over the OEM unit to handle elevated power levels without slipping, and the high-torque sprung hub assembly uses a double-sprung design with spring cover reliefs for flexibility and heat-treated components for long-term strength and durability.

Key Features:

• Pure Kevlar friction disc with steel backing for extended wear life and excellent drivability
• High-clamp pressure plate for increased torque holding capacity over stock
• Double-sprung hub with spring cover reliefs for drivetrain flexibility
• Heat-treated hub components for enhanced strength and durability
• Bearing and alignment tool kit included (application dependent)
• SFI approved — designed, hand-built, and tested in the U.S.A.

Recommended Driving Applications: Street, Drag Racing, Pulling, Autocross

The SPEC Stage 2 is the ideal step up from a stock or Stage 1 clutch for drivers seeking improved performance without sacrificing everyday usability. It represents a significant upgrade in torque capacity and longevity over the factory unit while maintaining the engagement feel expected in a street-driven vehicle.
