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 Honda GX200 & GX160
Designed by ARC Racing, these precision billet sidecovers strengthen critical engine areas, improve oil control, and enhance long-term durability for high-performance small-engine builds.
GX200 Billet Sidecover Features
The GX200 Billet Sidecover is CNC-machined from solid aluminum to reinforce the crankcase, improve oil flow, and provide superior sealing compared to cast factory covers, making it ideal for performance-focused builds and racing environments.
Oil Control & Crankcase Support Benefits
Integrated oil passages help manage lubrication under high RPM while the rigid billet structure minimizes flex, protecting bearings and internal components from premature wear during aggressive acceleration and sustained high-speed operation.
High-RPM Racing Durability
Built to withstand extreme engine stress, this sidecover maintains structural integrity at racing RPMs, preventing distortion common with stock covers and ensuring consistent performance in karting, minibike, and competition engines.
Compatible Engines
ARC billet sidecovers are engineered to fit popular small engine platforms used in racing, recreational builds, and high-performance upgrades, offering improved strength and reliability across multiple engine models.
- Honda GX200: The Honda GX200 Billet Sidecover delivers superior bottom-end reinforcement for one of the most widely used performance small engines, supporting higher RPM limits and aggressive camshaft setups without compromising engine stability.
- Honda GX160: For builders working with smaller-displacement platforms, the GX160 Billet Sidecover provides the same precision-machined strength and oil-management benefits, allowing GX160 engines to safely handle upgraded internal components.
- Predator 212 (Hemi & Non-Hemi): The Predator 212 Billet Sidecover fits both hemi and non-hemi variants, offering improved crankcase rigidity and lubrication control to support the higher horsepower commonly achieved in modified Predator engines.
- Predator 224: Performance enthusiasts using the larger Predator 224 benefit from enhanced crankshaft support and oil-flow stability, helping the engine maintain durability under higher compression, stroker, and racing configurations.
- GX200 Clone Engines: Many GX200-style clone engines share compatible mounting dimensions, making ARC billet sidecovers a reliable upgrade option for improving strength and longevity across a wide range of aftermarket engine platforms.
Why Upgrade to an ARC Billet Sidecover
Upgrading to a performance billet sidecover transforms the weakest structural area of stock small engines into a reinforced foundation designed for power, precision, and racing reliability.
- Improved Bottom-End Stability – Reduces crankshaft flex and bearing stress, keeping internal components aligned during high-load and high-RPM operation.
- Precision Machined Billet Aluminum – Provides tighter tolerances, superior sealing, and significantly greater strength than factory cast sidecovers.
- Designed for Performance & Racing Applications – Built to support cam upgrades, higher compression, and aggressive driving conditions without sacrificing durability.
Whether you're building a Honda GX200 Billet Sidecover setup, upgrading to a Predator 212 Billet Sidecover, or reinforcing your ARC GX200 Sidecover for competition, this is a critical performance improvement. Many racers rely on a GX200 Racing Sidecover to safely push their engines beyond factory limits.
