ACT XACT Streetlite Flywheel – Get the Ultimate Engine Response
Do you feel like your engine is being held back by a heavy factory flywheel? When you hit the gas, you expect an immediate reaction – not a delay. The ACT XACT Streetlite was engineered exactly for this moment.
As the most popular upgrade in the ACT lineup, the Streetlite series offers you the perfect balance: it is significantly lighter and stronger than OEM cast parts, yet retains enough mass to guarantee excellent drivability for daily street use and drag racing. By reducing rotating mass, your engine revs up lightning-fast, providing more aggressive acceleration and more precise gear shifts.
You’re not just investing in speed, but in safety. While cheap aluminum flywheels can warp, ACT relies on a one-piece forging. No loose parts, no compromises – just pure performance for your setup.

Important Installation Notes
Driving Experience: Expect significantly improved engine feedback. In some cases, slight gear chatter may occur at idle – a typical characteristic of performance flywheels that does not affect functionality.
Maintenance: A huge advantage of ACT steel flywheels is their serviceability. The friction surface can be easily resurfaced during a clutch change, so you don't have to buy a new wheel.
