Every pound on your competition car is another pound that your engine has to pull around the track. It might not seem like a lot, but it adds up quickly—and slows your top speed even more quickly. Put your powerplant on a high-performance diet with the ACT XACT Prolite Flywheel. Lighter than any other ACT Flywheel, it eases the load on your motor for electrifying throttle response and hair-raising acceleration.

More Milwaukee Mile than Main St, the ACT Prolite Flywheel is engineered from the ring gear up to excel at the track. CNC-machined from a precise CAD design, they feature a formidable one-piece construction that's rigid enough to withstand serious punishment while still spinning true across the RPM spectrum. Plus, they're dynamically balanced to ensure even weight distribution and efficient heat dissipation.

After almost two decades of crafting winning clutch upgrades for race teams the world over, ACT knows their way around both the machine shop and the speedway. So it should come as no surprise that every Prolite Lightweight Flywheel is SFI-certified and safe for hardcore road and rally racing. To top it off, ACT XACT Flywheels come with a 90-day warranty.
