Mahle Rings Perf 4.150in x 1.5MM .151 RW Plasma-Moly Steel Top Ring Moly Ring Set (48 Qty Bulk Pack)

This is a bulk pack of 48 Mahle OE performance piston ring sets, designed for engine builders and performance applications. Each set features top rings made from plasma-moly steel, measuring 4.150 inches in bore size with a 1.5mm thickness and a .151 inch ring land. The accompanying oil control rings are also moly-faced, ensuring a solid seal and efficient oil control within the cylinder bore.

Mahle OE uses plasma-moly steel for the top compression rings, a well-known material for its durability and resistance to wear, especially under higher cylinder pressures found in performance engines. This construction helps maintain a consistent seal between the piston and cylinder wall, which is crucial for optimal compression and power output. The moly coating on the oil control rings aids in reducing friction and wear against the cylinder walls, contributing to longer engine life and consistent oil consumption control. This bulk pack is ideal for shops or individuals undertaking multiple engine builds or working on high-performance V8 applications where precise ring sealing is paramount.

When installing these rings, ensure the cylinder bores are properly honed to the correct cross-hatch pattern and cleaned thoroughly. Refer to the specific engine build manual for correct ring gap specifications, as these can vary based on the intended application and materials used in the rest of the engine assembly. This bulk pack provides a cost-effective solution for professional engine builders needing a reliable, high-performance ring set for a variety of applications.
