Spec Clutch SN503H Stage 2+ Clutch Kit with Carbon-Kevlar Multi-Friction Disc

The SPEC SN503H Stage 2 PLUS Clutch Kit is engineered for modified performance engines that demand more torque capacity than a standard Stage 2 clutch can handle. Retaining the progressive, street-friendly engagement feel of the Stage 2, this kit steps up clamping force and disc friction material to accommodate higher-output powerplants — without sacrificing daily drivability or long service life.

At the heart of the Stage 2 PLUS is a composite multi-friction carbon-kevlar disc, which delivers superior heat resistance, extended wear life, and consistent torque transfer under demanding conditions. The high-clamp pressure plate increases holding capacity beyond the standard Stage 2, while the high-torque sprung hub and disc assembly helps absorb driveline shock and reduce chatter for a smoother, more controlled power transfer.

Key Features:

• High-clamp pressure plate for increased torque capacity over Stage 2
• Composite multi-friction carbon-kevlar friction disc for durability and heat resistance
• High-torque sprung hub and disc assembly for smooth engagement and reduced driveline shock
• Retains Stage 2 pedal feel for comfortable street and daily driving use
• Excellent wear characteristics for extended service intervals
• Complete kit includes pressure plate, disc, release bearing, and installation tool kit

Intended Use: Street, Drag Racing, Road Racing, Rally, Pulling, Autocross

The SPEC Stage 2 PLUS is the ideal upgrade for enthusiasts who have outgrown their Stage 2 clutch due to engine modifications, forced induction, or power adders, yet still want a clutch that performs well on the street every day.
