Spec Clutch SV491-2 Stage Performance Clutch Kit - 1 Organic Woven Disc

The SPEC SV491-2 Stage 1 Clutch Kit is engineered for bolt-on naturally aspirated and mildly modified forced induction engines, delivering near-stock daily drivability with a meaningful upgrade in holding power and longevity over OEM components.

At the heart of this kit is SPEC's signature high-clamp pressure plate, paired with a steel-backed, multi-compound woven organic friction disc. The organic lining is integrally molded for smooth engagement and excellent wear life, while the steel backing provides added strength under elevated clamp loads and operating temperatures. The high-torque sprung hub is double-sprung with spring cover relieves for drivetrain flexibility, and all hub components are heat-treated for lasting strength and durability.
