Mahle Rings 3.9027 X 1.5MM Plasma-Moly Steel Top Ring Moly Ring Set (48 Qty Bulk Pack)

This bulk pack gives you 48 complete sets of Mahle Piston Rings, featuring 3.9027-inch bore size and 1.5mm top rings. Each top ring is constructed from plasma-moly steel, known for its durability and resistance to wear, especially under high heat and stress. The accompanying oil control rings are also moly-coated, which helps to reduce friction and maintain a proper seal against the cylinder wall. This comprehensive set is ideal for engine builders or shops working on multiple engine rebuilds, ensuring you have high-quality components on hand.

Mahle has a long-standing reputation for producing well-built engine components, and these rings are no exception. The plasma-moly coating on the top rings is a notable feature that contributes to improved ring life and consistent performance. This coating helps to create a harder surface that resists scuffing and abrasion, which is crucial for maintaining compression and preventing blow-by over the life of the engine. The precise manufacturing ensures that each ring fits right within its groove, contributing to the overall efficiency and longevity of the engine assembly.

When undertaking a significant engine rebuild, having reliable piston rings is fundamental to achieving optimal performance and durability. This bulk pack of 48 sets from Mahle OE provides a cost-effective solution for projects requiring a large quantity of high-performance rings. Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to your specific engine's service manual for detailed installation procedures and specifications.
