Spec Clutch SF05SST Super Twin SS-Trim Multi-Disc Clutch and Flywheel Kit

The SPEC SF05SST Super Twin SS-Trim Multi-Disc Clutch Kit is engineered for high-output street and track applications demanding extreme torque capacity. Rated to handle 700 to 1,500 ft-lbs of torque, this twin-disc clutch and flywheel assembly delivers the power management needed for serious performance builds without sacrificing everyday drivability.

Despite its race-level capability, the Super Twin is designed for near-stock drivability with smooth, quiet engagement courtesy of its all-billet construction. Installation is straightforward with a true bolt-in, no-shimming/no-setup design, and the system operates maintenance-free under normal use. When service is eventually needed, the unit is fully rebuildable by SPEC or by the end user, with replacement components and rebuild services always available.

Key Features:

• Handles extreme torque loads from 700 to 1,500 ft-lbs — ideal for street, drag, drift, road race, time attack, pulling, and rally applications
• All-billet construction using aircraft-grade aluminum and high-carbon billet steel, CNC-milled to an industry-leading .001-inch tolerance for perfect balance and actuation
• Friction supplied by dampened, full-faced carbon-graphite discs (SS-Trim) with Carbon Composite/Kevlar® material and unsprung hub design
• Additional friction disc options available: organic, fiber, and full-metallic
• Flywheel and track-spec hardware included in every kit — no additional purchases required
• No-shimming, bolt-in installation — no special setup required
• Fully rebuildable by SPEC or the end user; replacement components always available
• Smooth and quiet operation from all-billet assembly
• Designed and hand-built in the U.S.A.

The SPEC Super Twin SS-Trim is the ideal solution for high-horsepower builds that demand competition-level clutch performance across all driving disciplines — from daily street driving to the most demanding track environments.
