ACT XACT Streetlite Flywheel for 1G DSM models is engineered to enhance engine response and acceleration while reducing rotational mass. Weighing 11.9 pounds compared to 21 pounds for stock units, this engine flywheel features one-piece construction for uniform heat transfer, improved durability, and easy resurfacing without the issues of multi-piece designs. Forged from high-quality chromoly steel, it is CAD-designed, CNC-machined, and dynamically balanced to ensure precision and smooth operation at high RPM. The material distribution optimizes strength, heat dissipation, and reduced inertia, while the induction-hardened integral ring gear maximizes gear life and starter engagement. Designed for both street and race use, this flywheel in automobile applications delivers reliable performance, OE to mild gear rattle, and long-lasting service, making it a lightweight, durable, and high-performance solution for enhanced drivability.
