Mahle Rings 4.0400 X 1.5MM Plasma-Moly Steel Top Ring Moly Ring Set (48 Qty Bulk Pack)

Mahle OE is known for making reliable engine components, and this bulk pack of 48 piston ring sets is no exception. If you're rebuilding multiple engines or working on a fleet, this pack gives you the quantity you need with the quality Mahle is known for. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall.

Each set features a 4.0400-inch bore size, with a 1.5mm top ring. The top rings are made from steel and treated with a plasma-moly coating. This coating is a hard, wear-resistant surface that helps the rings seat properly against the cylinder wall and reduces friction, which is important for engine longevity and performance. The second ring in the set is also a moly ring, further contributing to good oil control and sealing. This combination is a popular choice for many engine builds because it offers a good balance of durability and performance.

This is a bulk pack containing 48 complete sets of piston rings, making it ideal for shops or serious DIYers tackling multiple engine projects. Ensure you check manufacturer specifications for proper installation and compatibility with your specific engine build. Please note that these rings are not CARB approved and cannot be shipped to California.
