Spec Clutch SN85ET-2 Super Twin Multiplate Clutch Kit E-Trim

The Spec Clutch SN85ET-2 Super Twin Multiplate Clutch Kit (E-Trim) is engineered for high-output street and track applications demanding extreme torque capacity. Rated to handle 700–1,500 ft-lbs of torque, this twin-disc clutch system delivers race-proven clamping force while maintaining the pedal feel and drivability expected from a stock-style setup.

Built entirely from billet materials, the Super Twin features aircraft-grade aluminum and high-carbon billet steel components machined to industry-leading .001-inch tolerances for exceptional balance and precise actuation. Friction is delivered through dampened, full-faced carbon graphite discs, and the E-Trim specification offers an entry-level twin disc configuration designed for drivers who want multi-plate performance with everyday usability.
