Spec Clutch SV503H Stage 2 Plus Performance Clutch Kit

The Spec Clutch SV503H Stage 2 Plus Clutch Kit is engineered for modified engines that have outgrown the torque capacity of a standard Stage 2 clutch. Bridging the gap between the Stage 2 and Stage 3, this kit delivers the familiar, street-friendly engagement feel of the Stage 2 while providing a 15–20% higher torque capacity — making it an ideal upgrade for performance-built engines that demand more without sacrificing daily drivability.

The Stage 2+ disc uses a full-faced, multi-friction configuration with carbon semi-metallic material on one side and Kevlar® on the other, delivering excellent wear characteristics and strong, consistent grip across a wide range of driving conditions. The double-sprung hub features spring cover reliefs for added flexibility, along with heat-treated internal components for long-term strength and durability.

Kit Includes:

• High-clamp performance pressure plate
• Multi-friction disc — carbon semi-metallic / Kevlar® full-faced configuration
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Designed for Use With: OEM-style dual mass flywheels. If reusing an existing flywheel, the surface must be resurfaced prior to installation to ensure proper friction surface integrity. A minimum 450-mile break-in period of primarily city and stop-and-go driving is required before full-throttle engagement or aggressive launches.

Ideal Driving Applications: Street, Drag Racing, Road Racing, Rallye, Autocross, Pulling, and Drift. Designed, hand-built, and tested in the U.S.A.
