Mahle MS 87.50 mm1.2 1.2 2.8 mm Drop In Rings

These Mahle MS piston rings are built to specific dimensions: 87.50 mm bore size with a 1.2 mm, 1.2 mm, and 2.8 mm ring configuration. This precise sizing is crucial for proper sealing between the piston and cylinder wall, which directly impacts engine performance and oil consumption.

Mahle is a well-known name in engine components, and this ring set is designed for a drop-in installation, meaning they are intended to fit directly onto the piston without requiring special modifications. The different ring thicknesses are engineered to handle specific functions: the top ring handles the highest combustion temperatures and pressures, the second ring aids in oil control and helps break up carbon deposits, and the oil control ring scrapes excess oil from the cylinder wall.

When rebuilding an engine, choosing reliable piston rings is important for ensuring the longevity and performance of your build. These Mahle rings offer a well-built solution for many engine applications.
