Spec Clutch SY043F Stage 3 Plus Performance Clutch Kit

The SPEC SY043F Stage 3 Plus Clutch Kit is the flagship street/strip performance clutch solution for heavily modified engines that demand more torque capacity than the standard Stage 3 can support. Engineered for high-powered applications that still require daily drivability, the Stage 3+ delivers superior holding power with a more manageable and friendly engagement feel compared to full race-only clutch stages.

At the heart of this kit is a carbon semi-metallic full-faced friction disc that provides an outstanding balance of unparalleled service life, high friction coefficient, and excellent drivability in a single package. The hub is double-sprung with spring cover reliefs for added flexibility, and all hub components are heat-treated for long-term strength and durability under sustained high-load use.
