Spec Clutch SA443F Stage 3 Plus Performance Clutch Kit

The SPEC SA443F Stage 3 Plus (3+) Clutch Kit is the flagship street and performance clutch solution engineered for heavily modified engines that demand more torque capacity than the standard Stage 3 can deliver. Stepping beyond the Stage 3's 6-puck carbon semi-metallic design, the Stage 3+ features a full-faced carbon metallic friction disc that delivers a superior combination of long wear life, high friction coefficient, and excellent daily drivability — all in a single package.

The double-sprung hub design uses spring cover reliefs for added flexibility, while heat-treated components provide the strength and durability needed for high-stress street and race environments. A high-clamp pressure plate ensures firm, consistent engagement even under extreme torque loads, making this kit ideal for modified street builds and motorsport applications alike.

Kit Includes:

• High-clamp performance pressure plate
• Full-faced carbon metallic friction disc
• High-torque sprung hub and disc assembly
• Release bearing
• Installation tool kit

Intended Use:

• Street (including daily driving)
• Drag Racing
• Drifting
• Road Racing
• Autocross
• Pulling
• Rallye

SPEC clutches are designed, hand-built, and tested in the U.S.A. Every SPEC clutch kit is SFI approved. Note: If reusing an existing flywheel, the friction surface must be resurfaced prior to installation. A minimum 450-mile break-in period is required before full-throttle engagement or racing use.
