ACT Streetlite XACT Flywheel is engineered to enhance engine response, acceleration, and overall drivability for street and drag racing applications. Weighing just 11.2 pounds—nearly half the weight of a stock flywheel—this engine flywheel is forged, CNC-machined, and dynamically balanced for smooth operation at high RPM. Its one-piece construction ensures uniform heat transfer and eliminates issues with warped inserts or loose ring gears, while induction-hardened integral ring gears increase durability and starter engagement. Materials are carefully distributed to provide maximum strength, reduced rotational inertia, excellent heat tolerance, and rigidity. The flywheel maintains tight tolerances for concentricity and parallelism, with sufficient material behind the friction surface for superior heat capacity. ACT Streetlite flywheels are serviceable, resurfacing-friendly, and designed using advanced CAD and Finite Element Analysis, offering a lightweight, durable, and high-performance solution for any vehicle requiring a reliable and responsive engine flywheel.
