SPEC Super Twin multi-disc clutch and flywheel kits are designed for street and track use in vehicles with extreme horsepower and torque (700 to 1500 lbs.-ft.). They offer near-stock drivability, tremendous life expectancy, a no shimming/setup bolt-in installation, and maintenance-free operation.
With their all-billet construction, these assemblies are smooth and quiet. Super Twins are constructed with aircraft-grade aluminum and high-carbon billet steel milled to industry-leading .001 in. tolerances for perfect balance and actuation. Friction is provided by dampened, full-faced, carbon-graphite discs.
