The Honda 12000-Z0T-405 Cylinder Assembly is a genuine OEM Cylinder Assembly designed for GX160 horizontal shaft engines. As a direct Honda OEM component, this assembly is manufactured to the exact dimensions and tolerances required to maintain proper compression, bore geometry, and cooling passage integrity. If your existing cylinder has sustained bore wear, scoring, or damage that cannot be remedied by honing and re-ringing, this assembly provides the complete structural foundation to bring the engine back to full working condition.
Key Features
- Genuine Honda OEM Construction — manufactured to Honda's exact bore specifications, ensuring proper piston clearance, ring seal, and combustion chamber geometry that an undersized or out-of-spec bore cannot provide
- Direct Replacement for GX160 Engines — engineered specifically for the GX160 horizontal shaft engine, this assembly drops into place without alteration, preserving correct alignment of all mating engine components
- Serial Number Verification Recommended — Honda updates and supersedes cylinder assemblies at specific production breaks, so confirm your GX160 serial number against the fitment table before ordering
- Restores Compression and Engine Output — a worn or damaged cylinder allows combustion pressure to escape past the rings, resulting in hard starting, low power, and excessive oil consumption; replacing the cylinder assembly addresses the root cause directly
The cylinder assembly is the core structural casting of a four-stroke engine — it houses the piston and connecting rod, forms the combustion chamber walls, and provides the mounting surfaces for the cylinder head, crankcase, and ancillary components. Coolant and oil passages are cast directly into the assembly, so its integrity is fundamental to both lubrication and thermal management. When the cylinder bore wears beyond serviceable limits or sustains physical damage, no amount of ring replacement or carburetor tuning will restore lost compression — only a sound cylinder bore can do that, making this assembly one of the most consequential engine components a technician can replace.
