ACT Streetlite Flywheel 600145

The Advanced Clutch Technology (ACT) Streetlite Flywheel 600145 is engineered for automotive enthusiasts who demand performance without compromising durability. This flywheel is significantly lighter than the factory unit, offering a reduction in rotational mass that enhances engine response and acceleration. Crafted from chromoly steel, the 600145 is designed for both street and drag racing applications, providing a robust solution for high-performance builds.

Construction and Design

ACT utilizes a heat-treated forging process that enhances the strength and toughness of the flywheel. The induction-hardened ring gears extend the lifespan of the component, ensuring reliability under demanding conditions. The one-piece construction minimizes the risk of failure and optimizes heat transfer from the clutch disc, eliminating issues like warped inserts or loose ring gears.
