Description

Piston rings are designed to seal the combustion chamber of your engine so that gasses do not enter the crankcase and oil does not enter the combustion chamber. If your engine is burning oil, losing compression, or if you are rebuilding your engine, it is recommended that you replace your piston rings. This product is for a 4.187in bore diameter with a 3/16in EW CP20 oil ring.
