Piston Ring Kit

This piston ring set is designed to seal the combustion chamber and regulate oil consumption in your engine. We offer this specific component from MAHLE to support your engine repair or overhaul project. The set provides the necessary rings for a single cylinder, so you should calculate the total quantity needed based on your engine configuration.

The technical specifications feature a standard bore diameter of 77.00 mm. This set includes three distinct rings with heights of 1.20 mm, 1.20 mm, and 2.00 mm. These precise dimensions are critical for maintaining correct compression ratios and preventing combustion gases from escaping. The standard size specification indicates this is not intended for cylinders that require oversized components due to wear or machining.

Functionally, these rings play a vital role in heat transfer from the piston to the cylinder wall. They also scrape excess oil from the cylinder walls to maintain proper lubrication without burning oil. Installing new piston rings helps restore the original power output and efficiency of the engine by ensuring a tight seal during operation.

MAHLE produces this component with a focus on durability and precise fitment. The supplier code is 039 RS 10104 0N0. This part is compatible with a wide range of vehicles from the PSA Group. It fits numerous models including the Peugeot 207, 308, and 5008, as well as the Citroën C4, C5, and DS series.
