Engine Piston Ring Kit – ACDelco (89060378)

Engine Piston Ring Kit contains combustion in the cylinder bore and transfers force to the connecting rod. It is matched by bore diameter and ring groove width rather than by model year alone.

Replace the Piston Ring Kit when compression is low on one cylinder, when oil consumption climbs without an external leak, or when a teardown shows scoring in the bore. Measure the bore before ordering: standard size will not seal a cylinder that needs honing.

For this Piston Ring Kit the reference is 89060378, in our Pistons, Rings & Cylinders range. Compare it with the number on the part you are replacing rather than with a photograph.

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genuine ACDELCO, and this Piston Ring Kit keeps the original engineering number, which matters once a number has been superseded more than once.

Supplied as a kit rather than as an individual component, so check that you need the whole item before ordering.
