Description

South Bend Clutch Stage 2 Endurance clutch kits are recommended for daily and street use with an emphasis on rally and endurance racing. An SFI-approved single-mass flywheel is recommended for racing climate applications in order to achieve optimal performance (flywheel not included). Order the clutch kit recommended for your vehicle application.

Features include:

* Designed for the racing environment
* Pressure plate is precision-balanced for vibration-free operation at high-rpm
* Pressure plate fulcrum is altered for a positive disengagement and a quick shift
* Disc is engineered with a dual-damped design to provide accurate control when accelerating through corners
* Hybrid friction material with a full face Feramic (sintered iron) lining on the flywheel side and a high metal content organic lining on the pressure plate side
* Engagement is positive, yet buffered due to the high graphite content unique to Feramic facings
