The Honda 130A1-ZA0-004 Piston Ring Set (STD) is a genuine OEM component designed for GX360 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, EV4010, EV6010, and EVD4010 RV generators, and H4514, HT3813, and HT4213 lawn tractors. As a direct OEM replacement, this piston ring set is manufactured to Honda's exact specifications, ensuring the correct bore dimensions and ring tension for a proper seal. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes parts at production breaks and the standard (STD) sizing must match your engine's bore condition.
Key Features
- Correct Bore Sealing and Oil Control — as genuine Honda OEM rings, these are dimensioned to the exact compression and oil-control profiles Honda specifies for this bore, maintaining combustion pressure and preventing oil from migrating past the piston
- Standard (STD) Sizing — this set is sized for a standard, unworn bore; confirm your cylinder has not been bored oversize before installing
- Broad OEM Fitment — designed for GX360 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, EV4010, EV6010, and EVD4010 RV generators, and H4514, HT3813, and HT4213 lawn tractors; verify your serial number against the fitment table
- Restores Lost Compression — worn or broken rings allow combustion gases to blow past the piston, causing hard starting, excessive oil consumption, and loss of power; replacing with this set restores proper cylinder sealing and engine output
Piston rings sit in grooves machined around the piston and press outward against the cylinder wall to form a gas-tight seal. The compression rings at the top of the piston prevent combustion gases from escaping down into the crankcase, while the oil control ring below them scrapes excess oil from the cylinder wall and returns it to the sump. When rings wear, become stuck with carbon deposits, or break, compression drops, oil consumption rises, and the engine becomes difficult to start and runs poorly. Installing a fresh set of standard-bore rings restores the seal between the piston and cylinder, bringing combustion efficiency and oil control back to specification.
