Spec Clutch SD063H Stage 2 Plus Performance Clutch Kit

The SPEC SD063H Stage 2 Plus Clutch Kit is engineered for modified engines that demand more torque capacity than the standard Stage 2 can deliver. Bridging the gap between the Stage 2 and Stage 3, this kit provides a 15–20% higher torque capacity while retaining the smooth, street-friendly engagement feel that makes the Stage 2 series a favorite for daily-driven performance builds.

The disc features a full-face, multi-friction composite design with carbon semi-metallic material on one side and Kevlar on the other — a proven hybrid combination that delivers excellent wear characteristics and consistent engagement across a wide range of driving conditions. The high-clamp pressure plate increases clamping force over the standard Stage 2, while the double-sprung hub with spring cover reliefs absorbs driveline shock and provides flexibility under load. Hub components are heat-treated for enhanced strength and long-term durability.

What's Included:

• High-clamp performance pressure plate
• Composite multi-friction carbon/Kevlar clutch disc (full-face, sprung hub)
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Ideal Driving Applications:

• Street / Daily Performance
• Drag Racing
• Road Racing
• Rally
• Autocross
• Pulling

The SPEC Stage 2 Plus is the ideal upgrade for modified street cars and track builds that have outgrown a standard Stage 2 clutch but prefer to maintain near-OEM engagement quality without stepping into the more aggressive Stage 3 clutch characteristics.
