6603-PH ARC Billet Flywheel, Predator Hemi, 5-3/4" diameter 2.90lbs

ARC Racing 6603-PH billet flywheel designed for Predator 212 Hemi engines. Featuring a 5-3/4" finless design and lightweight 2.90 lb construction, this SFI-certified flywheel reduces drag and improves throttle response for kart racing and high-performance engine builds.

The ARC Racing 6603-PH billet flywheel is engineered specifically for Predator 212 Hemi engines used in kart racing and high-performance small engine builds. Precision-machined from billet aluminum and SFI certified, this flywheel replaces the factory cast flywheel with a stronger race-ready component designed for safe operation at elevated RPM.

With a 5-3/4" diameter and lightweight 2.90 lb construction, the 6603-PH uses a finless design that helps reduce air drag at high RPM. This design improves throttle response and efficiency in racing applications where reduced rotating resistance is important.

A powerful rare-earth magnet produces a strong ignition signal for reliable spark output while maintaining stable ignition timing under demanding racing conditions.

Important: This flywheel requires the #5982 coil relocation bracket and is not designed to work with a stock pull starter assembly.
