Spec Clutch SU052 Stage 2 Performance Clutch Kit with Kevlar Disc

The Spec Clutch SU052 Stage 2 Clutch Kit is a high-performance clutch solution engineered for mild to moderately modified naturally aspirated and power-adder engines. It delivers stock-like daily drivability while offering significantly improved wear characteristics and torque capacity over the OEM clutch — making it equally well-suited for spirited street driving where long service life is a priority.

Key Features:

• Pure Kevlar friction disc with steel backing — segmented or full-faced depending on application — for excellent drivability and extended service life
• High-clamp pressure plate provides increased clamping force for reliable power transfer under demanding conditions
• High-torque sprung hub and disc assembly with double-sprung design featuring spring cover relieves for flexibility and heat-treated components for strength and durability
• SFI Approved — every Spec clutch kit and flywheel meets SFI certification standards
• Suitable for street, drag, pulling, and autocross driving applications
• Bearing and alignment tool kit included (application dependent)

The Stage 2 Kevlar lining delivers the excellent daily drivability of the Stage 1, but with slightly longer service life and higher torque capacity — bridging the gap between a stock replacement and a dedicated performance clutch. Spec clutches are designed, tested, and manufactured in-house in their purpose-built U.S. facility, ensuring precise tolerances and quality control from pressure plate to disc.
