Spec Clutch SK163H Stage 2 Plus Clutch Kit with Kevlar/Carbon-Graphite Disc

The SPEC SK163H Stage 2 Plus Clutch Kit bridges the performance gap between the Stage 2 and Stage 3 clutch systems, delivering a compelling blend of everyday drivability and elevated torque capacity. Engineered around a multi-friction disc in a full-faced configuration, the disc combines carbon semi-metallic material on one side with Kevlar on the other — providing confident engagement feel while handling 15–20% more torque capacity than a standard Stage 2 setup.

The hub features a double-sprung design with spring cover reliefs for added flexibility, along with heat-treated components for long-term strength and durability. This kit is well-suited for a wide range of demanding applications including street driving, drag racing, autocross, road racing, rally, pulling, and drift.

Key Features:

• Hybrid friction disc — carbon semi-metallic on one side, Kevlar on the other, in a full-faced configuration
• High-clamp pressure plate for increased clamping force and torque handling
• 15–20% higher torque capacity over the Stage 2 clutch

The SPEC Stage 2 Plus is the ideal choice for drivers who need more than a Stage 2 can offer without sacrificing the streetable, progressive engagement that makes daily driving comfortable.
