Frequently Asked Questions – ARC Billet Crankshafts

What is the advantage of a billet crankshaft?

A billet crankshaft is precision-machined from high-strength alloy or 4340 chromoly rather than cast. This provides superior durability, improved structural integrity, better balance, and greater resistance to flex under sustained high-RPM racing conditions.

Are ARC billet crankshafts stronger than stock cranks?

Yes. ARC billet crankshafts are engineered for performance applications where elevated RPM, increased compression, and racing stress can exceed the limits of OEM cast crankshafts.

Which engines are ARC billet crankshafts compatible with?

ARC billet crankshafts are available for Predator 212 (Hemi & Non-Hemi), Predator Ghost, Predator 224, Honda GX200, GX390, 196cc Clone, Ducar, Tillotson, and select Briggs racing platforms. Always confirm journal size, stroke, taper, and fitment before ordering.

Do billet crankshafts increase horsepower?

Yes. When designed with increased stroke, a billet crankshaft can increase engine displacement, which directly increases torque and horsepower output. In addition to added stroke, improved balance and reduced flex in the rotating assembly allow the engine to operate more efficiently and reliably at higher RPM.

Are ARC billet crankshafts suitable for competitive kart racing?

Yes. ARC billet crankshafts are widely used in competitive kart racing, drag racing, and high-performance small engine builds where bottom-end durability, balance, and rotational stability are critical.

GX200 Crankshaft Specs and Fitment

Understanding crankshaft specifications ensures proper compatibility with your engine:

  • Stock Stroke: Approximately 2.123 - 2.125 inches
  • PTO Size: Must match your clutch or torque converter
  • Rod Journal Size: Must match your connecting rod 1.180 MAX
  • Engine Compatibility: GX200 and most 196cc clone engines

Matching these specs is essential for correct installation and long-term reliability.

OEM vs Performance Crankshafts (Know the Difference)

OEM GX200 crankshafts are designed for stock engine performance and reliability.

Unlike performance crankshafts:

  • OEM crankshafts are not dynamically balanced for high RPM racing
  • They are not intended for extreme performance builds
  • They are designed for standard operating conditions and longevity

If you are building a high-performance or racing engine, a billet or performance crankshaft may be required. For standard rebuilds and everyday use, OEM crankshafts are the correct choice.

Compatible Engines and Applications

GX200 crankshafts are widely used in:

  • Honda GX200 engines
  • 196cc clone engines
  • Go-karts and minibikes
  • Utility and recreational small engines

They are ideal for restoring engines used in both work and recreational applications.

Why Choose GX200 Crankshafts

Crankshafts are manufactured for consistency and reliability:

  • Built to OEM specifications for proper fitment
  • Trusted for engine rebuilds and replacements
  • Designed for durability in standard operating conditions

Our components are relied on by engine builders and small engine enthusiasts who need dependable parts that fit correctly and perform as expected.
