Spec Clutch SN443 Stage 3 Performance Clutch Kit - Carbon Semi-Metallic

The Spec Clutch SN443 Stage 3 Clutch Kit is engineered for heavily modified street and race engines that demand aggressive torque capacity without sacrificing daily drivability. Designed as the ultimate street/strip clutch, the Stage 3 delivers quick, confident engagement with a comfortable pedal feel and strong wear characteristics under both low and high stress conditions.

Key Features:

• High-clamp pressure plate for maximum clamping force and torque transfer
• Carbon semi-metallic friction disc — available in 4-puck or 6-puck configuration (6-puck is standard on most applications; 4-puck can be specified at time of order)
• High-torque sprung hub — double-sprung with spring cover relieves for added flexibility, plus heat-treated components for long-term strength and durability
• Holds up to 465 lb-ft of torque at the flywheel
• Kit includes high-clamp pressure plate, friction disc assembly, release bearing, and installation tool
• SFI Approved design

Recommended Driving Applications: Street, Drag, Drift, Road Race, Rallye, Pulling, Autocross

The SPEC Stage 3 sits within SPEC's street/strip performance range (Stages 1–3+), making it an ideal upgrade for high-output builds that still see regular street use. The sprung hub design absorbs drivetrain shock and provides the smooth, predictable engagement feel that separates it from full-race Stage 4 and 5 units.
