Spec Clutch SM483H Stage 2 Plus Clutch Kit - Carbon Kevlar Multi-Friction

The Spec Clutch SM483H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than a standard Stage 2 clutch can deliver, without sacrificing the street-friendly feel and drivability that Stage 2 is known for. Bridging the gap between the Stage 2 and Stage 3, the SM483H provides 15–20% higher torque capacity while maintaining smooth, predictable engagement for everyday driving.

At the heart of this kit is a composite multi-friction disc in a full-faced configuration, combining carbon semi-metallic material on one side and Kevlar on the other. This hybrid friction material delivers excellent wear characteristics, consistent torque transfer, and long service life under demanding conditions. The high-clamp pressure plate increases clamping force over stock to handle elevated power levels, while the double-sprung hub with spring cover reliefs absorbs drivetrain shock and provides flexibility for a more refined engagement feel. Heat-treated hub components add strength and durability for sustained high-performance use.

Kit Includes:

• High-clamp performance pressure plate
• Multi-friction carbon semi-metallic / Kevlar composite disc
• High-torque double-sprung hub and disc assembly
• Release bearing
• Installation tool kit

Intended Use:

• Street
• Drag Racing
• Road Racing
• Rally
• Pulling
• Autocross

The SM483H is the ideal upgrade for enthusiasts running modified engines who need more torque handling than a Stage 2 allows, but want to preserve the daily drivability and engagement quality that a full Stage 3 setup sacrifices. Whether you're building a high-output street car or a dual-purpose track machine, this kit delivers the performance headroom to match your build.
