Piston Ring Kit – Mopar (68440324aa)

Piston Ring Kit 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 Kit 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 Kit is listed as part 68440324aa (Pistons, Rings & Cylinders). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is MOPAR dealer-sourced stock rather than an equivalent, so the number on the Piston Ring Kit traces straight back to the manufacturer.

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