Spec Clutch SF961 Stage Performance Clutch Kit - 1

The Spec Clutch SF961 Stage 1 Clutch Kit is engineered for bolt-on naturally aspirated engines and mildly modified forced induction applications, delivering stock-like daily drivability with a meaningful upgrade in holding power and wear life over OEM clutch components.

At the heart of the SF961 is a high clamp pressure plate paired with a steel-backed, multi-compound woven organic friction disc. The organic lining provides smooth, progressive engagement and excellent service life, while the steel backing adds structural rigidity under high clamp loads and elevated operating temperatures. The high-torque sprung hub and disc assembly features a double-sprung design with spring cover reliefs for added flexibility and heat-treated components for long-term durability.

• High clamp performance pressure plate

The Stage 1 is Spec's entry-level performance clutch, offering the ideal balance of drivability and performance for daily-driven vehicles that also see occasional track or competition use. The familiar pedal feel makes it a direct, driver-friendly upgrade over a worn or stock clutch.
