ARC 6664 Predator 459 Billet Flywheel

The ARC 6664 Billet Flywheel is designed specifically for the Predator 459cc engine and provides a major performance upgrade over the heavy factory flywheel. Precision-machined billet construction provides the strength and reliability needed for modified, racing, and high-performance engine applications.

One of the biggest advantages of the ARC 6664 is its substantial reduction in rotating weight. This flywheel is over 8 lbs lighter than the stock Predator 459cc flywheel. Reducing rotating mass allows the engine to accelerate quicker and provides improved throttle response compared with the heavy factory flywheel.

The 6664 also features +4° ignition timing over stock, making it an excellent choice for performance-oriented Predator 459cc engine builds.

Whether you're building a racing engine, performance go-kart, minibike, or another modified Predator 459cc application, the ARC 6664 provides a lighter, stronger billet flywheel designed specifically for this engine platform.
