Mahle Rings 4.0750 Bore Dia 1.2MM Edge Width Steel Plasma Moly Top Ring Moly Ring Set

This Mahle OE piston ring set includes everything you need to replace the rings on your pistons. It features a 4.0750 inch bore diameter and a 1.2mm edge width for the top ring. The top rings are made of steel with a plasma moly coating, and the second rings also feature a moly coating. These materials and coatings are chosen to help the rings seal effectively against the cylinder wall, which is crucial for proper engine compression and oil control.

Mahle has been a trusted name in engine components for a long time, and this ring set is built to their standards. The combination of steel and plasma moly on the top ring offers good wear resistance and helps maintain a seal under various operating conditions. The moly coating on the second ring also aids in reducing friction and improving sealing. When you're rebuilding an engine or replacing worn-out components, a solid set of piston rings like these is essential for restoring lost power and ensuring the engine runs smoothly.
