Spec Clutch SZ422 Stage 2 Performance Clutch Kit with Kevlar Disc

The Spec Clutch SZ422 Stage 2 Clutch Kit is engineered for drivers who demand strong performance without sacrificing everyday usability. Ideal for mildly to moderately modified naturally aspirated and power-adder engines, the Stage 2 is equally well-suited to stock power levels where long service life and smooth daily drivability are priorities.

Key Features:

• Segmented or full-faced pure Kevlar® friction disc with steel backing for excellent wear resistance and higher torque capacity
• High-clamp pressure plate for improved clamping force over stock
• Double-sprung hub with spring cover reliefs for smooth, flexible engagement
• Heat-treated hub components for long-term strength and durability
• High-torque sprung hub and disc assembly for confident power transfer
• Includes release bearing and installation tool kit

The Stage 2's Kevlar disc lining delivers stock-like engagement feel and drivability comparable to the Stage 1, while offering meaningfully longer service life and greater torque handling capacity — making it a smart upgrade for street, drag, autocross, and pulling applications.
