Mahle Rings Perf Plasma Moly Steel HV385 Top Ring 3.553in x 1.0MM .143in RW Ring Set (48 Qty Bulk)

Mahle is a well-known name in the automotive world, especially for their engine components. They're known for making parts that meet or exceed original equipment standards. This set of Mahle HV385 top piston rings continues that tradition, offering a plasma moly steel construction designed for performance applications.

These rings measure 3.553 inches in bore diameter, with a 1.0mm thickness and a 0.143-inch ring groove width. The plasma moly coating is a key feature here, providing a hard, wear-resistant surface that helps reduce friction and improve durability. This is particularly important in high-performance engines where heat and stress are greater. This bulk set includes 48 rings, making it suitable for engine builders working on multiple projects or high-volume shops.

When rebuilding an engine, the piston rings are critical for sealing the combustion chamber, controlling oil consumption, and transferring heat. Choosing well-made rings like these from Mahle OE can make a significant difference in the longevity and performance of your engine build. Please note that these rings are not CARB approved and cannot be shipped to California.
