South Bend Clutch KFM09-HD-TZ Stage 2 Endurance Kevlar Clutch Kit 10-Spline

The South Bend Clutch KFM09-HD-TZ is a Stage 2 Endurance performance clutch kit engineered for drivers who demand reliable, high-torque capability on both the street and the track. Rated at 520 ft-lbs of torque, this kit is purpose-built for rally and endurance racing applications while remaining streetable for daily use.

At the heart of this system is a 275mm (10.83") full-face Kevlar disc featuring South Bend's proprietary Dual Damped design for precise control during hard acceleration and cornering. The friction material uses a hybrid construction — a full-face Feramic (Sintered Iron) lining on the flywheel side and a high metal content Organic lining on the pressure plate side. This combination delivers positive, buffered engagement thanks to the high graphite content unique to Feramic facings, minimizing harsh engagement while maximizing grip at high RPM.

The precision-balanced diaphragm pressure plate is engineered for vibration-free operation at high RPM, and its modified fulcrum promotes quick, positive disengagement for faster, cleaner shifts. A 10-spline input shaft (1.06" diameter) configuration is included in this kit. An SFI-approved single mass flywheel is recommended for optimal performance (sold separately).
