• Exclusive four-stage heat treatment on all diaphragms for increased strength and durability
• Adjustable design to compensate for disc wear and ensure equal disengagement of both discs
• Performance street rigid-hub discs with premium organic friction materials containing high copper content for superior heat transfer
• Steel-backed lining on discs for enhanced burst strength and durability
• Heat-treated chrome-moly hub for maximum strength and longevity
• Carefully selected rivet design and materials to withstand high stress and torque loads
• CNC-machined, dynamically balanced flywheel included for smooth installation and operation
• 100% clamp load tested and dynamically computer balanced for reliable high RPM performance

Construction & Design:

The ACT Twin Disc HD Street Clutch Kit is built with precision and quality materials to meet the demands of high-performance street driving. The twin disc setup features rigid-hub discs crafted from premium organic friction materials enriched with copper to improve heat dissipation and reduce fade.
