What makes plasma-moly steel and moly coatings beneficial?

Plasma-moly steel offers excellent wear resistance and durability for the top ring, helping it withstand high temperatures and pressures. The moly coating on the second ring assists in creating a strong seal against the cylinder wall and helps manage oil, reducing friction and preventing blow-by.

Can these rings be shipped to California?

No, this product is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This bulk pack gives you 48 sets of Mahle OE Performance Piston Rings, each designed for a 4.140-inch bore. You're getting top rings made from plasma-moly steel, known for its durability and resistance to wear, paired with moly-coated second rings. This combination is built to handle the demands of high-performance engines, ensuring a solid seal between the piston and cylinder wall for optimal compression and oil control.

Mahle has a long history in engine building, and these rings reflect that experience. The plasma-moly coating on the top ring is a tough surface that works well with various cylinder wall materials, helping to reduce friction and heat buildup. The moly coating on the second ring further aids in sealing and oil scraping, which is crucial for preventing blow-by and excessive oil consumption, especially under stress. This set is intended for engine builders who need a reliable, well-built ring package for multiple builds or performance applications where consistent sealing is paramount.

Because this is a bulk pack of 48 sets, it's ideal for shops or serious DIYers undertaking multiple engine rebuilds or performance projects. Ensure you check manufacturer specifications for proper installation and compatibility with your specific pistons and cylinder bore finish. Please note that this product is not CARB approved and cannot be shipped to California.
