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.

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.
Predator 212 Hemi Billet Flywheels for Kart Racing Engines
ARC Racing billet flywheels designed for Predator 212 Hemi engines provide the strength and reliability required for kart racing and high-performance small engine builds. These flywheels are precision-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 in racing engines. ARC billet flywheels replace these cast components with a stronger billet aluminum flywheel that delivers improved ignition stability, consistent spark performance, and increased durability in demanding racing environments.
Compatible Engine Platforms
- Predator 212 Hemi (Gen 2 – cast aluminum valve cover)
- Kohler CH270 (select flywheel models)
Because Predator engines are produced in both Hemi and Non-Hemi versions, it is important to select the correct flywheel designed specifically for the Hemi engine configuration.
Why Choose ARC Billet Flywheels?
- Precision-machined billet aluminum construction
- SFI certified for racing safety
- Stable ignition timing and strong magnetic signal
- Designed for high-RPM kart racing engines
- Trusted by engine builders and racers worldwide
Whether you're building a competitive kart racing engine or upgrading a Predator 212 Hemi performance build, ARC Racing billet flywheels provide the durability, ignition stability, and reliability serious racers demand.
Predator 212 Hemi Billet Flywheels – Frequently Asked Questions
Why upgrade to a billet flywheel?
Billet flywheels are significantly stronger than stock cast flywheels. Upgrading to an ARC billet flywheel improves ignition stability and provides safer operation in high-RPM racing engines.
Are ARC billet flywheels SFI certified?
Yes. ARC Racing billet flywheels are SFI certified, meaning they meet recognized racing safety standards for high-performance small engine applications.
What Predator engines do Hemi flywheels fit?
These flywheels are designed specifically for Predator 212 Hemi engines with the cast aluminum valve cover (Gen 2). They are not compatible with Predator 212 Non-Hemi engines.
Will a billet flywheel increase horsepower?
A billet flywheel does not directly create horsepower, but it improves ignition stability and allows engines to safely operate at higher RPM, which can improve overall performance in racing engines.
Do ARC flywheels work with stock ignition coils?
Many ARC Predator Hemi flywheels work with the stock pull starter and ignition coil, but always verify compatibility in the individual product listing before installation.
