WARNING: This product can expose you to chemicals that are known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, visit www.P65warnings.ca.gov.Upgrading your street or drag strip machine often reveals the limitations of a heavy, sluggish dual mass factory flywheel. The ACT 601160 XACT Streetlite Flywheel addresses this power-robbing weight by replacing the stock unit with a lightweight, high-strength forged chromoly steel piece. Weighing only 15.2 pounds, this single-mass design reduces rotating inertia to noticeably improve engine response and acceleration. The one-piece construction eliminates the common failure points of multi-piece designs, ensuring uniform heat transfer and preventing warped inserts or loose ring gears.
