About this part

Product Details

When you're rebuilding the top end of your engine, getting the piston rings seated properly is key to good compression and oil control. This Mahle OE Moly Ring Set is built for that job. It features steel top rings with a moly coating, which helps them break in smoothly and maintain a good seal against the cylinder wall over time.

The 3.927-inch bore size and 1.2mm top ring width are common dimensions for many performance engine builds. The moly coating on these rings is a practical choice because it reduces friction during the critical break-in period, helping to prevent scuffing and ensuring the rings seat evenly. This means you're more likely to achieve consistent cylinder sealing and better oil control right from the start.
