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.

Find the Right GX200 Crankshaft for Your Engine

Choosing the correct GX200 crankshaft ensures your engine runs properly and reliably.

Whether you're completing a rebuild or replacing a damaged component, ARC Racing offers OEM-quality crankshafts designed for straightforward installation and long-term use.
