SPEC Clutch SS235-4 Stage 5 Full-Metallic Clutch Kit

The SPEC SS235-4 Stage 5 clutch kit represents the peak of single-disc performance clutch technology, designed for extreme racing applications and high-output builds. This clutch kit features a full-metallic disc with the highest possible friction coefficient, delivering maximum grip and power transfer under the most demanding conditions.

Key Features:

• Solid 12-rivet hub with heat-treated assembly for strength and durability
• Full-metallic friction material with highest possible friction coefficient
• High-clamp pressure plate for maximum holding power
• Includes bearing and tool kit
• SFI approved for competitive racing applications

Performance Characteristics:

Stage 5 is recommended for race-only applications. While street-drivable, this clutch is not street-friendly, making it best suited for dedicated race vehicles, extreme street builds, drag racing, pulling competitions, and autocross events. The full-metallic construction provides exceptional thermal resistance and maintains consistent engagement even under repeated high-temperature cycles and aggressive launches.

Applications:

This Stage 5 clutch kit is engineered for extreme performance scenarios including drag racing, road course competition, pulling events, and autocross. The aggressive engagement characteristics and maximum torque capacity make it the ideal choice for vehicles operating at the limits of single-disc clutch technology.
