Spec Clutch SH411 Stage Performance Clutch Kit - 1 Organic Full Face

The Spec Clutch SH411 Stage 1 Clutch Kit is a high-performance clutch upgrade engineered for bolt-on naturally aspirated and mildly modified forced induction engines. Designed to deliver stock-like daily drivability without sacrificing performance, the Stage 1 is SPEC's entry-level performance clutch — ideal for drivers who want a meaningful upgrade over OEM while retaining smooth, predictable engagement for everyday driving.

At the heart of the SH411 is a carbon-Kevlar®-based, high-performance organic friction disc lining that provides smooth engagement and excellent service life. The lining features an integrally bonded steel backing for strength under high clamp loads and elevated temperatures. The double-sprung hub uses spring cover reliefs for flexibility and heat-treated components for long-term strength and durability.
