Spec Clutch SZ042 Stage 2 Performance Clutch Kit

The Spec Clutch SZ042 Stage 2 Clutch Kit is engineered for mild to moderately modified naturally aspirated and power-adder engines, while also delivering exceptional longevity and stock-like feel at factory power levels. It is an ideal choice for spirited street driving, drag racing, pulling, and autocross competition.

At the heart of this kit is a segmented or full-faced pure Kevlar® friction disc with steel backing, offering excellent daily drivability with slightly longer service life and higher torque capacity than a Stage 1 clutch. The double-sprung hub features spring cover reliefs for drivetrain flexibility, and all hub components are heat-treated for long-term strength and durability.

Key Features:

• High-clamp pressure plate for positive, confident engagement
• Pure Kevlar® friction material with steel-backed disc for extended wear life
• Double-sprung hub with spring cover reliefs for smooth power transfer
• Heat-treated hub components for superior strength and durability
• Includes bearing and installation tool kit (where applicable)
• SFI approved

Recommended Use: Street, Drag, Pulling, Autocross

Designed, hand-built, and tested in the USA, the Spec SZ042 Stage 2 kit delivers a performance upgrade that retains excellent street manners while handling the demands of modified and high-performance driving environments.
