Spec Clutch SF271CJ Stage Performance Clutch Kit - 1 High Clamp Organic

The Spec Clutch SF271CJ Stage 1 Clutch Kit is a high-performance, street-friendly clutch upgrade engineered for bolt-on naturally aspirated engines and mildly modified forced induction applications. Delivering stock-like daily drivability with significantly improved holding power, the Stage 1 is SPEC's entry-level performance clutch — and the ideal choice for drivers who want a noticeable upgrade without sacrificing everyday comfort or pedal feel.

At the heart of the Stage 1 kit is a carbon Kevlar-based, multi-compound woven organic friction disc featuring an integrally bonded steel backing. This construction provides smooth, predictable engagement and excellent wear life under both daily driving conditions and spirited performance use. The double-sprung hub uses spring cover relieves for flexibility, with heat-treated components throughout for long-term strength and durability.
