If you're looking to ditch that heavy stock flywheel and make your ride a bit more lively, the ACT XACT Flywheel Streetlite 600480 is a solid choice. This thing is noticeably lighter than what you’re used to, which means better engine response and quicker acceleration. You’ll feel the difference, especially if you’re into spirited driving or even hitting the drag strip. The design is all about durability too—ACT really nailed it with the materials here. They’ve balanced strength, heat tolerance, and rigidity, so you’re not just getting a lightweight part; you’re getting something that can handle the heat of performance driving.

One of the best parts? This flywheel is serviceable. You can resurface it when it starts to wear down, so you won’t have to fork over cash for a new one every time. Plus, the one-piece construction means there’s less chance of failure. No more worrying about warped inserts or loose ring gears, which can be a real headache.

Here’s what you can expect:

• Improved engine response and acceleration that you’ll notice right away, plus a bit of that OE to mild gear rattle that adds character.
• Heat-treated forging gives it the strength and toughness you need, while the induction-hardened ring gears ensure it lasts longer.
• Forged, CNC machined, and dynamically balanced for smooth performance at high RPMs.
• Recommended for both street and race use—this flywheel doesn’t play around.
