Piston Ring Set - Priced Per Piston

A piston ring is a split ring that fits into a groove on the outer diameter of a piston. The three main functions of piston rings in reciprocating engines are, sealing the combustion/expansion chamber, supporting heat transfer from the piston to the cylinder wall and regulating engine oil consumption.

Compression testing is the best way to check the condition of an engine with some mileage on it. If your compression numbers across the cylinders are low, it's time to replace your piston rings.

This is a piston ring set of +0.50mm size for each cylinder. So as many cylinders as you have, that's how many sets you will need.
