Spec Clutch SH133F Stage 3 Plus Clutch Kit - Carbon Composite Full-Face Honda

The Spec Clutch SH133F Stage 3 Plus is the flagship single-disc clutch kit for high-powered Honda applications that demand maximum torque capacity without sacrificing street manners. Engineered for heavily modified street and race engines that have outgrown the standard Stage 3, the Stage 3 Plus steps up with a full-faced carbon semi-metallic disc that delivers outstanding friction coefficient, exceptional service life, and a more manageable, daily-drivable engagement compared to traditional puck-style clutches.

Unlike the Stage 3's puck disc, the Stage 3 Plus uses a full-faced clutch disc for improved engagement quality and long-term durability, making it the preferred choice when you need serious torque capacity alongside real-world drivability. The hub is double-sprung with spring cover reliefs for added flexibility, and all hub components are heat-treated for maximum strength and fatigue resistance under sustained high-stress use.

• High-clamp performance pressure plate
