Spec Clutch SN46ET Super Twin E-Trim Multi-Disc Clutch and Flywheel Kit

The SPEC SN46ET Super Twin E-Trim is a high-performance multi-disc clutch and flywheel kit engineered for street and track applications demanding extreme torque handling. Rated to handle 700–1,500 ft-lbs of torque (E-Trim: up to 1,400 ft-lbs at the flywheel), this twin-disc assembly delivers the power management needed for serious builds without sacrificing daily drivability.

Built from aircraft-grade aluminum and high-carbon billet steel machined to an industry-leading .001-inch tolerance, the Super Twin achieves exceptional rotational balance and precise actuation. Full-faced, dampened carbon graphite friction discs provide consistent, predictable engagement across all performance driving scenarios.
