Spec Clutch SR984 Stage 4 Race Clutch Kit - 3/4/6 Puck Carbon Semi-Metallic

The Spec Clutch SR984 Stage 4 Clutch Kit is a race-focused, solid hub performance clutch designed for heavily modified engines that demand maximum torque capacity and instantaneous engagement. Built in the USA, this kit is engineered for competitors who prioritize holding power and response over street manners.

Key Features:

• Solid 8-rivet rigid hub — a solid hub evolution of the Stage 3, heat treated for enhanced strength and durability
• High clamp pressure plate — delivers increased clamping force for high-torque applications
• Available in 3, 4, or 6 puck carbon semi-metallic friction disc — choose 3-puck for the lightest rotational mass, 6-puck for the smoothest engagement, or 4-puck as an ideal compromise between the two
• SFI Approved — every Spec clutch kit and flywheel carries SFI certification
• Torque capacity up to 363 ft-lbs
• Kit includes: high clamp pressure plate, friction disc, carrier assembly, release bearing, and installation tool kit

Intended Use:

• Drag Racing
• Drifting
• Road Racing
• Rallye
• Pulling
• Circle Track

Please Note: The Stage 4 is a race-only clutch. The rigid hub results in harsh engagement characteristics that are not suitable for daily street driving. This kit is recommended for dedicated race and competition vehicles only.
