Mahle Rings Perf 4.170in 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 piston ring sets, specifically designed for engine rebuilding applications. Each set features a 4.170-inch bore size, with a 1.5mm top ring thickness and a .151-inch oil ring thickness. The top rings are constructed from plasma-moly steel for improved durability and performance, paired with moly rings for effective oil control and reduced friction.

Mahle OE is a well-known name in engine components, and these rings are built to meet the demands of performance engine builds. The plasma-moly steel used in the top rings offers a strong, wear-resistant surface that can handle higher operating temperatures and pressures often found in performance applications. The moly coating on the oil rings helps to seat quickly and maintain a consistent seal against the cylinder wall, which is crucial for preventing oil blow-by and maintaining proper lubrication. This bulk pack is ideal for shops or builders working on multiple engines or those who prefer to have high-quality replacement parts on hand.

When rebuilding an engine, proper ring selection is critical for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. These Mahle OE rings are designed to perform these functions effectively, contributing to the overall health and longevity of your rebuilt engine.
