Mahle Rings Perf Gas Nitrid Steel Oil Ring 4.0650in x 3.0MM .127inRW Plain Ring Set (48 Qty Bulk)

This bulk package contains 48 Mahle OE steel oil ring sets, each measuring 4.0650 inches in bore diameter with a 3.0mm thickness and a .127 inch rail width. These rings are designed for performance gasoline engines and feature a nitride steel construction for improved durability and wear resistance. The nitride treatment creates a harder surface on the ring, which helps it withstand the high temperatures and pressures found in performance applications, while also reducing friction against the cylinder wall. This means you get a more efficient seal and better oil control, contributing to overall engine health and performance.

Mahle is a well-known name in engine components, and these rings are built to their OE specifications, meaning they are made to fit and function as the original equipment manufacturer intended. The steel material offers a strong and reliable option for rebuilding or upgrading your engine's piston assembly. Because this is a bulk package of 48 sets, it's ideal for machine shops or engine builders who frequently work on multiple engines of the same specification. Ensure your engine is properly sealed and lubricated with these well-made oil rings from Mahle OE.

Please note that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual or consult with a professional mechanic for specific installation procedures and compatibility details for your particular engine build.
