Spec Clutch SA863H Stage 2+ Performance Clutch Kit

The Spec Clutch SA863H Stage 2+ Clutch Kit is engineered for modified engines that demand more torque capacity than the standard Stage 2 can support, while still preserving excellent street manners and daily drivability. With a rated torque capacity of 545 ft-lbs, this kit bridges the gap between the Stage 2 and Stage 3, delivering a 15–20% higher torque capacity than the Stage 2 without sacrificing the smooth, predictable engagement that makes it suitable for everyday driving.

The SA863H features a composite multi-friction disc in a full-faced configuration — carbon semi-metallic on one side and Kevlar on the other — pairing aggressive grip with manageable wear characteristics. The double-sprung hub includes spring cover reliefs for flexibility and uses heat-treated components throughout for long-term strength and durability.

Kit Includes:

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

Intended Use:

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

The Stage 2+ is the ideal choice for daily-driven performance vehicles running forced induction, power adders, or high-output naturally aspirated builds that have outgrown a Stage 2 clutch but do not require the more aggressive engagement of a full Stage 3. Note: A proper 500-mile break-in period is recommended, and the flywheel should be resurfaced or replaced prior to installation.
