SPEC Clutch SA442S-2 Stage 2 Kevlar Clutch Kit for Audi S4 / RS4

The SPEC SA442S-2 Stage 2 Clutch Kit is a high-performance clutch system engineered for the Audi S4 and RS4 with the 4.2L V8 engine. Designed for drivers who demand more holding power than a stock or Stage 1 clutch can provide, the Stage 2 delivers an impressive torque capacity of 498 ft-lb while maintaining the everyday drivability expected from a street clutch.

Key Features:

• Pure Kevlar friction disc with steel backing — available in segmented or full-faced configuration depending on application
• Higher torque capacity than Stage 1, with improved service life
• Double-sprung hub with spring cover reliefs for flexibility and heat-treated components for superior strength and durability
• Designed for use with the OEM-style Dual Mass Flywheel (DMFW)
• High-clamp pressure plate engineered to handle performance driving demands
• Alignment tool included for straightforward installation
• SFI Approved clutch kit and components

The Stage 2 is ideal for street, drag, pulling, and autocross applications. It delivers the increased clamping force needed for modified or power-added engines without sacrificing the smooth, progressive engagement that makes a clutch livable on the street. A minimum 450-mile break-in period with primarily city and stop-and-go driving is required before full-throttle engagement. Resurfacing the existing flywheel is required unless a new SPEC flywheel is used.
