The ACT 600225 XACT Streetlite flywheel delivers noticeably improved engine response and acceleration with OE-to-mild gear rattle. Heat-treated forging provides strength and toughness, while induction-hardened ring gear teeth maximize service life. The one-piece construction reduces potential failure points and provides uniform, efficient heat transfer away from the clutch disc, eliminating the warped inserts or loose ring gears seen on multi-piece flywheels. It is forged, CNC-machined, and dynamically computer-balanced for smooth high-RPM reliability and is recommended for both street and race use.

FAQ
Why doesn't this listing show specific vehicle fitment?
The ACT600225 is cataloged by ACT as a standalone Streetlite flywheel without a published vehicle-specific fitment table. Confirm bolt pattern, pilot bore, and tooth count against the intended application before ordering.
Can this flywheel be used for race applications?
Yes, ACT rates the Streetlite flywheel line for both street and race use.
Why is the ring gear induction-hardened?
Induction hardening the ring gear teeth increases wear resistance so the starter ring gear holds up to repeated engagements over the life of the flywheel.
Is this flywheel serviceable?
XACT flywheels are designed with a one-piece construction that provides uniform heat transfer and can generally be resurfaced; confirm resurfacing limits for this specific part before machining.
