Spec Clutch SFGT54 Stage 4 Carbon-Graphite Racing Clutch Kit

The Spec Clutch SFGT54 Stage 4 Clutch Kit is a high-performance, race-focused clutch designed for serious competition driving. Built as a solid hub evolution of the Stage 3, this kit features a heat-treated, solid 8-rivet hub and disc assembly engineered to handle the extreme demands of drag racing, road racing, rallye, drifting, and pulling. With SFI approval, the SFGT54 meets the rigorous safety and performance standards required for sanctioned motorsport events.

The Stage 4 is available in your choice of 3, 4, or 6-puck disc configurations, allowing you to tailor clutch behavior to your specific racing application. The 3-puck disc offers the lightest rotating mass, while the 6-puck configuration provides the smoothest engagement of the three options and remains technically street-drivable — though the rigid solid hub makes it unsuitable for regular street use. The 4-puck configuration strikes a balance between the two, delivering a strong compromise of weight savings and engagement quality.

Key Features:

• Solid 8-rivet hub — heat-treated for maximum strength and durability under race conditions
• Carbon-graphite friction material — withstands extreme operating temperatures to prevent clutch failure
• High-clamp pressure plate — delivers aggressive, precise engagement and disengagement
• Available in 3, 4, or 6-puck disc configurations — choose your ideal balance of weight and drivability
• SFI approved — meets sanctioned motorsport certification requirements
• Includes bearing and alignment tool kit — everything needed for installation

The SFGT54 is a race-only clutch kit — Spec recommends Stages 1 through 3+ for street/strip use, with Stages 4 and 5 reserved strictly for competition applications. Professional installation is recommended.
