The ACT ZM10-HDSS kit pairs ACT's most popular Heavy Duty pressure plate with ACT's most popular Performance Street disc for a dependable street/light-track upgrade. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load and reduce deflection, and every diaphragm goes through a four-stage heat-treating process for consistent, long-lasting performance. Precision cover stampings add rigidity and consistency to the pressure plate assembly. The included Performance Street disc uses premium organic friction material with high copper content for better heat transfer, plus a steel-backed lining for greater burst strength and durability, giving smooth street-friendly engagement with a meaningful increase in torque capacity over stock.
