Spec Clutch SN333F-5 Stage 3 Plus Clutch Kit SR20DET-S15 OE Dual Mass Flywheel

The SPEC SN333F-5 Stage 3+ Clutch Kit is SPEC's flagship performance clutch for high-powered street and competition vehicles demanding confident, manageable engagement without sacrificing drivability. Engineered specifically for the SR20DET-S15 2.0L turbo platform and designed for use with the OE dual mass flywheel, this kit features a rigid hub disc with a full-faced carbon semi-metallic friction material that delivers an exceptional combination of longevity, high friction coefficient, and everyday usability in a single package.

The high-torque hub assembly uses a rigid configuration compatible with the factory dual mass flywheel, with heat-treated internal components engineered for strength and long-term durability under demanding conditions. A high-clamp pressure plate works in concert with the carbon semi-metallic disc to provide the torque holding capacity needed for modified and boosted applications. This kit is rated to hold 540 lb-ft of torque at the flywheel, making it well-suited for heavily modified SR20DET builds.

Key Features:

• Carbon semi-metallic full-faced friction material — outstanding life, friction coefficient, and drivability
• Rigid hub design — engineered for compatibility with OE dual mass flywheel
• Heat-treated hub components — built for strength and durability under high loads
• High-clamp pressure plate — maximizes clamping force and torque transfer
• 540 lb-ft flywheel torque capacity — handles heavily modified and turbocharged SR20DET applications
• Bearing and tool kit included — everything needed for a complete installation
• Ideal for street, drag, drift, autocross, road racing, pulling, and rallye

SPEC clutches are manufactured in the USA using advanced fabrication processes held to strict tolerances. The Stage 3+ represents the optimal balance between aggressive performance capability and street-friendly engagement — recommended for stages 1–3+ on street/strip applications.
