Spec Clutch SD88SST Multiplate Super Twin Clutch Kit

The SPEC SD88SST Super Twin Multiplate Clutch Kit is a high-performance, multi-disc clutch system engineered for enthusiasts and racers who demand maximum torque capacity and durability beyond what a single-disc clutch can provide. SPEC's Super Twin design uses two clutch discs to dramatically increase clamping force and torque holding capacity while maintaining drivability characteristics suited for both street and track use.

This kit is available in multiple friction material trim levels, allowing you to match the clutch performance characteristics to your specific application and driving style:

• SS-Trim – Sprung Street: Designed for street performance with a smooth engagement and excellent daily-driving manners
• P-Trim – Sprung Performance: A step up in grip, ideal for modified street vehicles and occasional track use
• ST-Trim – Solid Street: Aggressive holding capacity with a firmer pedal feel, suited for high-horsepower street builds
• E-Trim – Solid Endurance: Race-grade friction material optimized for sustained high-heat track environments
• ET-Trim – Solid Endurance Track: Maximum torque capacity for full competition and extreme horsepower builds

SPEC clutch kits are manufactured to exacting tolerances using premium materials, ensuring consistent performance lap after lap. The Super Twin configuration is ideal for high-output engines where a single-disc clutch has reached its torque limits.
