What is the primary function of an oil ring assembly?

The oil ring assembly's main job is to scrape excess oil from the cylinder walls as the piston moves down. This prevents oil from entering the combustion chamber, which helps reduce oil consumption and exhaust smoke.

Why is the chrome plating important on these rings?

Chrome plating on piston rings offers increased hardness and wear resistance. This helps the rings last longer and maintain a consistent seal against the cylinder wall, even under demanding conditions.

Mahle is a well-known name in engine components, and this oil ring assembly is built to perform.

The standard tension design ensures a reliable fit and function in a wide range of engine applications where a performance rebuild is being done.

When rebuilding an engine, the oil control system is just as important as the compression rings. These Mahle oil ring assemblies are designed to help keep oil where it belongs, preventing excessive consumption and blow-by.
