Upgrade your Mazda’s drivetrain with the ACT 600641 XACT Streetlite flywheel, engineered to provide noticeably quicker engine response and improved acceleration compared with a stock flywheel. Its reduced rotating mass helps the engine rev more freely while maintaining the strength, heat tolerance, and rigidity required for demanding street and drag racing applications. The Streetlite design delivers a practical balance of performance and drivability, with OE to mild gear rattle characteristics when paired with a compatible ACT clutch system.
ACT manufactures this flywheel from a heat-treated forging for enhanced strength and toughness. The one-piece construction eliminates common failure points associated with loose ring gears or warped inserts while promoting uniform, efficient heat transfer from the clutch disc. An induction-hardened ring gear is designed for long service life, and the flywheel is forged, CNC machined, and dynamically computer balanced to support smooth, reliable operation at high engine speeds. The ACT 600641 is serviceable and can be resurfaced when appropriate, helping reduce the need for additional replacement parts during future clutch maintenance.
This ACT XACT Streetlite flywheel is recommended for street and race use and must be used with an ACT pressure plate and clutch disc. It is listed for select Mazda 3 applications from 2007 through 2013, as well as select Mazda 6 applications from 2006 through 2007; verify vehicle and drivetrain compatibility before installation. The product is backed by ACT’s one-year limited warranty, providing added confidence in its construction and performance. Professional installation is recommended, along with proper inspection of the clutch, transmission, and related mounting components before assembly.
