Spec Clutch SV875 Stage 5 Clutch Kit - Full-Metallic Sintered Iron Disc

The Spec Clutch SV875 Stage 5 Clutch Kit is engineered for extreme performance applications including drag racing, pulling, and heavily modified engines. Featuring a full-metallic sintered iron disc with the highest available friction coefficient, this kit delivers maximum torque capacity of 684 ft-lbs for applications that demand uncompromising clamping force and grip.

The Stage 5 is SPEC's most aggressive single-disc clutch offering. Its solid 12-rivet rigid hub assembly is heat-treated for superior strength and durability under high-load, high-temperature racing conditions. While technically street-drivable, this clutch is not designed for street use due to its harsh, aggressive engagement characteristics — it is a purpose-built race clutch.

Kit Includes:

• High-clamp pressure plate
• Full-metallic full-faced sintered iron disc with unsprung/rigid hub
• Release bearing
• Installation tool kit

Key Features:

• Maximum torque capacity: 684 ft-lbs
• Highest possible friction coefficient for maximum grip
• Solid 12-rivet hub assembly — heat-treated for strength and durability

The SPEC SV875 Stage 5 is best suited for dedicated race builds where maximum holding power is the priority. For heavily modified applications or slipper/progressive clutch needs, consulting a SPEC technical specialist prior to ordering is strongly recommended to ensure proper configuration for your specific build.
