Construction & Design

The SPEC Stage 3+ Clutch Kit features a meticulously engineered design that combines high-performance materials with advanced manufacturing techniques. The full-faced friction disc utilizes a semi-metallic carbon composite, which offers a high friction coefficient and excellent wear characteristics. This material choice ensures reliable engagement and longevity, even under aggressive driving conditions.

The clutch components are heat-treated to withstand the intense heat generated during high-power applications, preventing warping or failure. The sprung hub design, depending on the application, helps absorb torsional vibrations, reducing stress on drivetrain components and enhancing overall driving comfort. The relived spring cover design improves heat dissipation, further extending the lifespan of the clutch assembly.
