Performance Benefits

MAHLE's Performance Metric Ring Program offers professional engine builders and performance enthusiasts precision-ground piston rings manufactured to exact specifications. The chrome-faced top compression ring provides superior wear resistance and maintains optimal compression seal under high-stress conditions. The second compression ring aids in both sealing and oil control, while the 2.8mm three-piece oil control ring delivers exceptional oil management without excessive ring tension or power loss.

These rings are designed to seal the combustion chamber effectively, preventing combustion gases from entering the crankcase while controlling oil consumption. Whether building a performance street engine or a competition powerplant, MAHLE's precision manufacturing ensures proper ring-to-cylinder wall contact, rapid break-in, and long-term reliability.
