600590 is a Streetlite flywheel from ACT's XACT lineup, built to be considerably lighter than the factory flywheel while remaining the most durable option in ACT's flywheel range. Weight is distributed to maximize strength, lower rotating inertia, and hold up to heat, delivering noticeably improved throttle response and acceleration with only OE-to-mild gear rattle. The forged, CNC-machined, and dynamically balanced construction is heat-treated for toughness and uses an induction-hardened ring gear, making it a good fit for street or race use, and like all XACT flywheels it can be resurfaced rather than replaced at service time.

FAQ
Can this flywheel be paired with an aftermarket clutch?
Yes. It is built to work with quality aftermarket clutches as well as OE-spec units, provided the clutch is matched to the correct step height, ring gear tooth count, and flywheel thickness. If it is part of an ACT clutch kit, the flywheel that kit specifies should be used.
What is a flywheel step, and why does it matter?
The step is the distance between the friction surface and the pressure plate mounting point, and it sets the correct working range for the pressure plate. Depending on the vehicle it can be an up-step, down-step, or flat design, so matching the correct step is critical to proper clutch function.
Can this flywheel be resurfaced?
Yes, it can be resurfaced the same way as a factory flywheel using a flywheel grinder, removing no more than about 0.040 in (1.02 mm) of material while preserving the correct step height.
Is this flywheel suitable for daily street driving?
Yes. The Streetlite is engineered for street and race use, with OE-to-mild gear rattle and a noticeable gain in throttle response and acceleration over the stock flywheel.
