Spec Clutch SP842 Stage 2 Kevlar Clutch Kit

The Spec Clutch SP842 Stage 2 Clutch Kit is engineered for drivers who demand more from their drivetrain without sacrificing everyday usability. Designed for mild to moderately modified naturally aspirated and forced induction engines, this kit delivers a noticeable step up in torque capacity and wear life over the Stage 1 — while maintaining smooth, street-friendly engagement.

Key Features:

• Pure Kevlar® friction disc — segmented or full-faced with steel backing for superior grip and longevity
• High-clamp pressure plate for increased holding power over the factory clutch
• Double-sprung hub with spring cover reliefs for flexibility, plus heat-treated components for strength and durability
• High-torque sprung hub and disc assembly (application dependent)
• Bearing and alignment tool kit included for straightforward installation
• 23-spline input shaft compatibility (1.031 in. shaft diameter)

Compared to the Stage 1, the Stage 2 offers slightly longer service life and higher torque capacity while preserving excellent daily drivability — making it an ideal choice for performance enthusiasts who split time between the street and the track. Suitable for street driving, drag racing, pulling, and autocross.

Spec Clutch products are designed, tested, and manufactured in-house in the USA, engineered to precise tolerances for consistent performance across a wide range of applications.
