Benefits of Billet Flywheels in Racing

  • Improves throttle response and acceleration for faster corner exit and stronger launch performance.
  • Reduces rotating mass to deliver quicker power transfer and improved engine responsiveness.
  • Withstands higher RPM without flex, cracking, or failure compared to stock cast flywheels.
  • Provides consistent ignition timing for optimized spark delivery and peak combustion efficiency.
  • Enhances engine cooling under sustained high-speed and competitive racing conditions.

Flywheel Compatibility by Engine Type

ARC billet flywheels are engineered for precise fitment and high-RPM reliability across popular small engine platforms, including:

  • Predator 212cc (Hemi & Non-Hemi), Predator Ghost, and Predator 224
  • Honda GX160 / GX200 / GX390
  • 196cc Clone, Ducar, and Tillotson Engines
  • Select Briggs & Stratton Models

Correct flywheel fitment is essential for safety, ignition timing accuracy, and optimal performance in competitive kart racing and high-performance small engine builds. Always verify engine specifications before installation.

How to Choose the Right ARC Flywheel

  • Confirm your engine model and configuration (Hemi vs. Non-Hemi) to ensure proper crankshaft fitment and ignition alignment.
  • Match timing specifications to your ignition setup for optimal spark advance and engine efficiency.
  • Select according to racing class rules to remain compliant with karting or sanctioning body regulations.
  • Consider flywheel weight based on your application — lighter options for quicker throttle response or heavier models for smoother circle track performance.
  • All ARC billet flywheels are SFI-certified, providing built-in racing safety compliance without the need to choose between certified and non-certified models.
  • Ensure the RPM rating matches your build to maintain reliability and durability in high-performance applications.
