Whether its for a full rebuild or some standard maintenance, the proper engine components are needed to make sure your vehicle is running smooth.

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.
