Spec Clutch SJ383H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SJ383H Stage 2 Plus Clutch Kit is a high-performance upgrade engineered to bridge the gap between the Stage 2 and Stage 3 clutch systems. It delivers the smooth drivability and refined engagement quality of the Stage 2 while adding 15–20% more torque capacity, making it ideal for enthusiasts who demand more from their drivetrain without sacrificing everyday usability.

At the heart of this kit is a multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side with Kevlar on the other. This hybrid friction pairing maximizes grip, wear resistance, and heat management under demanding conditions. The hub is double-sprung with spring cover reliefs for added flexibility, and all internal components are heat-treated for long-term strength and durability.

Key Features:

• High-clamp pressure plate for increased clamping force and positive engagement
• Hybrid carbon semi-metallic and Kevlar friction disc in full-faced configuration
• Double-sprung hub with spring cover reliefs for smooth, flexible power transfer
• Heat-treated internal components for superior strength and durability
• 15–20% higher torque capacity over the Stage 2 clutch
• Bearing and tool kit included for complete installation
• Designed, hand-built, and tested in the U.S.A.

The Stage 2 Plus is well-suited for a wide range of performance driving disciplines including street, drag racing, autocross, road racing, rally, pulling, and drifting. It's an excellent choice for drivers seeking a meaningful performance upgrade that remains civilized enough for regular street use.
