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

GX200 Crankshaft FAQ
What does a GX200 crankshaft do?
It converts the up-and-down motion of the piston into rotational force to power the engine.
What is the stock GX200 crankshaft stroke?
Approximately 2.123 - 2.125 inches.
Are OEM crankshafts balanced?
OEM crankshafts are manufactured to factory balance standards but are not dynamically balanced like performance crankshafts.
Do I need a performance crankshaft?
For standard use and rebuilds, an OEM crankshaft is the best choice.
Briggs & Stratton Billet Flywheels for Racing Engines
ARC Racing billet flywheels designed for Briggs engines provide the strength and reliability required for competitive racing engines. These flywheels are CNC-machined from billet aluminum and SFI certified to ensure safe operation in engines running at elevated RPM.
Factory cast flywheels are not designed for sustained high-RPM operation commonly found in racing applications. ARC billet flywheels replace these cast components with a high-strength billet aluminum flywheel that delivers improved durability, stable ignition timing, and consistent spark performance.
Compatible Briggs Engine Platforms
- Briggs Flathead Racing Engines (3HP / 5HP)
- Briggs Animal Racing Engines
- Briggs Model 28 / 31 / 33 OHV Engines
- Briggs Vanguard & Intek V-Twin Engines
- Briggs Jr. Dragster Engines
These engines are widely used in kart racing, Jr. dragster, and racing mower competition where reliable ignition timing and durable rotating components are critical for performance and safety.
Why Choose ARC Billet Flywheels?
- Precision-machined billet aluminum construction
- SFI certified for racing safety
- Strong rare-earth magnets for reliable ignition timing
- Designed for high-RPM racing engines
- Trusted by racers and professional engine builders
Whether you're building a kart racing engine, Jr. dragster engine, or racing mower engine, ARC Racing billet flywheels deliver the durability, ignition stability, and performance serious racers demand.
Briggs Billet Flywheels – Frequently Asked Questions
