Spec Clutch SP042 Stage 2 Kevlar Clutch Kit

The Spec Clutch SP042 Stage 2 Clutch Kit is a premium street/strip performance clutch solution engineered for mild to moderately modified naturally aspirated and power-adder engines. It delivers the ideal balance between daily drivability and increased torque capacity, making it an excellent choice for spirited street driving, drag racing, autocross, and pulling applications.

At the heart of the Stage 2 kit is a segmented or full-faced pure Kevlar friction disc with steel backing. Compared to a Stage 1 clutch, this Kevlar lining provides equally smooth engagement and street-friendly drivability while adding notably longer service life and a higher torque threshold. The hub design — sprung or rigid depending on application — features double-sprung construction with spring cover reliefs for added flexibility, along with heat-treated components throughout for enhanced strength and durability.

Kit Includes:

• High-clamp performance pressure plate
• Pure Kevlar friction disc with steel backing (segmented or full-faced)
• High-torque sprung hub and disc assembly
• Throwout/release bearing
• Alignment tool for installation

Intended Use:

• Street / Daily Driving
• Drag Racing
• Autocross
• Pulling

SPEC clutches are manufactured and developed for specific driving environments, with every clutch kit and flywheel carrying SFI approval. The Stage 2 sits within SPEC's lineup of street-oriented stages (1, 2, 2+, 3, 3+), offering more holding power than Stage 1 without sacrificing the smooth, predictable engagement that makes it suitable for everyday use.
