Description

The SB13-HDR4 kit combines ACT’s Heavy Duty pressure plate with a 4-pad rigid race disc for high-performance race use. The diaphragm-style pressure plate increases clamp load, reduces deflection, and maximizes clutch life. The 4-pad rigid disc is constructed with high-quality ceramic friction material and a heat-treated chrome-moly hub for strength and durability. Engagement is aggressive, and the lightweight, rigid design allows quicker shifts and smooth, trouble-free service. This 4-pad rigid disc is ideal for smaller clutch sizes in smaller engines.
