Spec Clutch SS184 Stage 4 Performance Clutch Kit - Carbon Semi-Metallic

The Spec Clutch SS184 Stage 4 Clutch Kit is a race-grade drivetrain solution engineered for heavily modified engines demanding maximum torque transfer and instantaneous engagement. Designed specifically for competitive motorsport use, this kit delivers the aggressive holding power required in high-output applications where reduced rotating mass and immediate clutch response are critical.

Key Features:

• High-clamp pressure plate for maximum clamping force and torque capacity
• Carbon semi-metallic friction disc available in 3, 4, or 6-puck configurations — choose 3-puck for minimum rotating weight, 6-puck for the smoothest engagement, or 4-puck as an optimal compromise
• High-torque solid hub and carrier assembly with eight-rivet construction and heat-treated components for strength and durability
• Rigid 2-piece clutch disc design delivers instantaneous engagement for maximum performance on track
• Bearing and tool kit included for straightforward installation
• SFI Approved — designed, hand-built, and tested in the U.S.A.

Intended Use:

• Drag Racing
• Road Racing
• Drifting
• Rally / Rallycross
• Pulling
• Circle Track

Important Note: The Stage 4 is a race-only clutch system. Due to the rigid hub design and instantaneous engagement characteristics, this kit is not recommended for street driving. It is best suited for dedicated race builds and heavily modified performance vehicles where drivability is secondary to maximum torque handling.
