Briggs Flathead Flywheels – Frequently Asked Questions
Why upgrade to a billet flywheel on a flathead engine?
Billet flywheels are significantly stronger than stock cast iron flywheels. Upgrading to an ARC billet flywheel improves ignition stability and allows flathead racing engines to safely operate at higher RPM.
Are ARC flathead flywheels SFI certified?
Yes. ARC billet flywheels are SFI certified and designed for racing engines operating at elevated RPM levels.
What engines do these flywheels fit?
ARC flathead flywheels are designed for Briggs & Stratton 3HP and 5HP flathead engines commonly used in kart racing and Jr. dragster engines.
Do billet flywheels increase horsepower?
Billet flywheels do not directly increase horsepower, but they improve ignition stability and allow engines to safely operate at higher RPM in racing applications.
Do ARC flathead flywheels allow timing adjustment?
Some ARC flathead flywheels use adjustable timing hubs that allow racers to advance or retard ignition timing to fine-tune engine performance.
