The three parts a GX390 rental engine needs most often, in one part number — complete air filter, complete recoil starter assembly and cylinder head.
What's in the kit
- Complete Air Filter (GX390) — KPHAFC390
- Complete Starter Assembly (GX390, round) — KPHRSAR390
- Cylinder Head Assembly (GX390) — KPHCYH390
What you save
The kit is priced 15% below the same three parts bought one by one — the exact saving is shown next to the price.
How to save more
- Take the rebuild kit instead if the head is coming off. The GX390 rebuild kit covers the head with the camshaft and gaskets that go with it, at the same 15%, and saves stripping the engine twice.
- Order a season's worth at once. Filters and starters get replaced on schedule, not on failure — buying them together means one carriage charge instead of a delivery a month.
Fits Honda GX390. Need the flat starter instead? Order KPHRSAF390 on its own.
