What is the primary function of piston rings?

Piston rings seal the combustion chamber to maintain compression, scrape excess oil from the cylinder walls, and transfer heat from the piston to the cylinder wall. This ensures efficient engine operation and longevity.

Why are these rings made of steel?

The steel top ring offers improved strength and durability, especially in high-performance engines where cylinder pressures can be significantly higher than stock. This helps the ring maintain its shape and sealing ability under stress.
