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.

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.
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.
Billet Sidecovers for Predator 224 & Ducar 224 Engines
ARC billet sidecovers are built to reinforce one of the most stressed areas of a high-performance small engine. When stock cast sidecovers flex or fail under load, a billet upgrade provides the rigidity required to maintain crankshaft alignment and consistent oiling at elevated speeds.
The Predator 224 Billet Sidecover is purpose-built for racers who want to eliminate weak points and protect their engine’s bottom end while maximizing performance potential.
Designed for 224cc Non-Hemi Engines
These billet sidecovers are designed exclusively for non-hemi 224cc engine platforms. Fitment and internal clearances are optimized for this configuration, ensuring proper oil flow, crankshaft support, and compatibility with performance internals commonly used in racing applications.
High-RPM Performance & Crankcase Support
As RPM increases, crankcase stability becomes critical. A billet side cover helps reduce crankshaft journal flex, minimizing wear and maintaining precise alignment. The ARC Predator 224 Sidecover is engineered to support high-RPM operation, making it ideal for competitive racing and aggressive performance builds.
Precision Machined Billet Aluminum Construction
Each sidecover is precision-machined from high-quality billet aluminum. This construction delivers superior strength, improved heat resistance, and consistent tolerances compared to stock cast components.
Compatible 224cc Engines
ARC billet sidecovers are designed to work across multiple popular 224cc platforms, making them a versatile upgrade for a wide range of builds.
Predator 224 Non-Hemi
The Predator 224 non-hemi engine is a popular choice for karting, mini bikes, and racing applications. Upgrading to a billet sidecover significantly improves bottom-end strength and oil control, especially when paired with billet rods, performance cams, and high-RPM valve train components.
Ducar 224
The Ducar 224 Billet Sidecover provides the same structural benefits for Ducar engines, which are widely used in racing and performance-oriented builds. This upgrade helps ensure consistent operation under load while supporting aggressive tuning and RPM increases.
224cc Clone Engines
Many 224cc clone engines share a similar architecture and benefit from a billet side cover upgrade. Builders using clone platforms can improve durability and reliability by replacing the factory side cover with a precision-machined billet option designed for performance use.
Performance Benefits of Upgrading to a Billet Sidecover
A billet sidecover upgrade delivers multiple performance and reliability advantages that become increasingly important as engine output rises, whether you’re building a Predator or Ducar 224 Side Cover application for racing or high-performance use.
- Improved Bottom-End Stability: Reinforces the crankshaft support area to reduce flex at high RPM, helping maintain proper alignment and reduce bearing wear.
- Enhanced Oil Control: Promotes consistent oil flow and lubrication during hard acceleration and sustained high-speed operation.
- Increased Durability Under Racing Conditions: A Predator 224 Side Cover Upgrade offers significantly greater resistance to cracking and fatigue compared to stock cast sidecovers, making it ideal for aggressive performance builds.
