Spec Clutch SN601 Stage Performance Clutch Kit - 1

The Spec Clutch SN601 Stage 1 Clutch Kit is an ideal performance upgrade for daily-driven Nissan vehicles running bolt-on naturally aspirated or mildly modified forced induction engines. Engineered to deliver stock-like pedal feel with significantly improved holding power and wear characteristics, the Stage 1 is the perfect step up from a worn factory clutch without sacrificing everyday drivability.

At the heart of the kit is SPEC's signature high-clamp pressure plate, paired with a steel-backed, multi-compound woven organic friction disc featuring an integrally bonded steel backing for strength under high clamp loads and elevated temperatures. The high-torque double-sprung hub includes spring cover reliefs for enhanced flexibility, while heat-treated hub components ensure long-term durability under demanding conditions.

• High-clamp performance pressure plate
