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.

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 212 Non-Hemi Engines
ARC billet sidecovers replace the factory cast side cover with a rigid, precision-machined billet aluminum design. This upgrade reduces flex, supports crankshaft alignment, and helps maintain consistent performance under extreme conditions. The Predator 212 Non-Hemi Billet Sidecover is built for racers who demand reliability when RPM, heat, and load increase.
Dual Bearing Billet Sidecover Design
A dual bearing configuration adds an extra layer of crankshaft support where it matters most. The Dual Bearing Predator 212 Sidecover helps minimize movement at high RPM, reducing wear on internal components and promoting smoother operation during aggressive racing conditions.
Built for High-RPM Racing Applications
As RPM climbs, the crankcase becomes one of the most stressed areas of the engine. ARC Racing sidecovers are designed for sustained high-speed operation, making them ideal for karting, minibike racing, and competitive small-engine builds where failure is not an option.
Precision Machined Billet Aluminum Construction
Each sidecover is CNC-machined from high-quality billet aluminum for superior strength and consistent tolerances. Compared to stock cast pieces, billet construction offers improved heat resistance and structural integrity. The ARC Predator 212 Sidecover delivers long-term durability even in demanding race environments.
Performance Benefits of Upgrading Your Predator 212
A billet side cover upgrade delivers measurable advantages that directly impact performance, reliability, and engine life.
- Increased Bottom-End Stability: Reinforces crankshaft support to reduce flex and maintain proper alignment at high RPM.
- Improved Oil Control & Sealing: Helps manage oil flow more effectively during acceleration, braking, and sustained racing conditions.
- Enhanced Strength Under Load: Designed to withstand higher horsepower, increased torque, and aggressive tuning without cracking or distortion.
For builders looking to maximize reliability while pushing performance limits, a Predator 212 Billet Sidecover is a smart and proven upgrade.
Compatible Engines
ARC Racing billet sidecovers are engineered for popular non-hemi 212 platforms commonly used in racing and performance builds.
Predator 212 Non-Hemi
The Predator 212 non-hemi engine is widely used for its simplicity and upgrade potential. A billet side cover strengthens the crankcase and supports additional performance modifications, such as billet rods, high-lift cams, and heavier valve springs. Upgrading to a Predator 212 Non-Hemi Side Cover helps protect the engine as power and RPM increase.
212cc Non-Hemi Clone Engines
Many clone engines share a similar architecture with the Predator 212 and benefit from the same billet sidecover upgrades. A 212cc Non-Hemi Billet Sidecover provides improved durability and oil control for clone-based builds used in racing, recreational, or custom applications.
