Piston Ring Set – Kia (23040-3CHA0)

Piston Ring Set is a reciprocating component that seals the combustion chamber. Clearance and surface finish decide whether it seals correctly, so the bore has to be measured before a replacement is chosen.

Replace the Piston Ring Set when a leak-down test shows air escaping past the rings, when the skirt is scuffed, or when ring lands are cracked. Check the ring end gap in the bore it will run in.

This Piston Ring Set is listed as part 23040-3CHA0 (Pistons, Rings & Cylinders). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

The stock here is genuine KIA, and this Piston Ring Set keeps the original engineering number, which matters once a number has been superseded more than once.

This is sold as an set; if only one component has failed, confirm whether the single part is available separately.
