Spec Clutch SB60SST Super Twin SS-Trim Multiplate Clutch Kit

The SPEC SB60SST Super Twin SS-Trim Clutch Kit is engineered for high-performance street and track applications, purpose-built to handle extreme horsepower and torque loads ranging from 700 to 1,500 ft-lbs. Despite its race-ready capability, the Super Twin delivers near-stock drivability, making it equally at home on daily driven performance cars as it is on dedicated competition vehicles.

Key Features:

• Rated for 700–1,500 ft-lbs of torque — suitable for highly modified and forced-induction builds
• Near-stock drivability with smooth, quiet engagement thanks to full billet construction
• Constructed from aircraft-grade aluminum and high-carbon billet steel, milled to an industry-leading .001-inch tolerance for perfect balance and precise actuation
• Friction provided by dampened, full-faced carbon graphite discs
• Available friction material options: organic, fiber, and full metallic
• No shimming or setup required — true bolt-in installation
• Maintenance-free operation with long service life
• Fully rebuildable by SPEC or the end user; replacement components and rebuild services are always available
• Flywheel and track-spec hardware included in each kit

Intended Applications:

• Street, drag racing, drifting, road racing, time attack, pulling, and rallye

The SPEC Super Twin SS-Trim is the ideal upgrade for builds that have outgrown single-disc clutch solutions. Its billet construction, precision machining, and versatile friction material options make it one of the most capable and durable multiplate clutch systems available for extreme-performance use.
