Spec Clutch SD08PT Super Twin Multi-Disc Clutch Kit P-Trim

The Spec Clutch SD08PT Super Twin P-Trim is a premium multi-disc clutch and flywheel kit engineered for high-output street and track builds demanding between 700 and 1,500 ft-lbs of torque. Designed for serious performance without sacrificing daily driveability, the Super Twin delivers near-stock pedal feel and engagement quality in an all-billet, maintenance-free package.

Every Super Twin assembly is constructed 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 delivered through dampened, full-faced carbon graphite discs, providing exceptional grip and consistent performance across a wide range of operating conditions. The P-Trim configuration uses a carbon graphite disc material suited for street and moderate track applications.
