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
