ACT twin disc kits endure an exclusive four-stage, heat-treating process on all diaphragms. The ACT twin disc kits features the ability to adjust for disc wear and provides equal disengagement for discs. The Performance street rigid-hub discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. The chrome-moly hub is heat-treated for strength and durability. Rivet design and materials are carefully selected for maximum strength. All ACT twin disc kits include a CNC-machined and dynamically balanced flywheel to ensure trouble-free installation and operation.
