Spec Clutch SD06SST Super Twin SS-Trim Multi-Plate Clutch Kit

The SPEC SD06SST Super Twin SS-Trim Multi-Plate Clutch Kit is engineered for high-output street and track applications, capable of handling between 700 and 1,500 lb-ft of torque. Despite its extreme performance envelope, the Super Twin delivers near-stock drivability with smooth, quiet operation thanks to its all-billet construction.

The assembly is built from aircraft-grade aluminum and high-carbon billet steel, machined to an industry-leading .001-inch tolerance for perfect rotational balance and precise actuation. Friction is supplied by dampened, full-faced carbon-graphite discs, with organic, fiber, and full-metallic disc options also available to match your specific application demands.

Installation is straightforward with a no-shimming, no-setup bolt-in design, and the unit requires no ongoing maintenance. When service is eventually needed, the Super Twin is fully rebuildable — either by SPEC or by the end user — with replacement components and rebuild services always available.
