What is the primary function of these piston rings?

These piston rings serve three main functions: they seal the combustion chamber to prevent gas leakage, they control oil consumption by scraping excess oil from the cylinder walls, and they help transfer heat from the piston to the cylinder wall for cooling.

Why is the top ring made of plasma-moly steel and the second ring moly-coated?

Plasma-moly steel offers enhanced durability and wear resistance, especially in high-performance applications. The moly coating on the second ring further reduces friction and wear, contributing to a longer lifespan for both the rings and the pistons.

What does the '48 Qty Bulk Pack' mean for my engine build?

This means you receive 48 individual sets of piston rings in one package. This is ideal for engine builders or shops that work on multiple engines or are performing high-volume rebuilds, ensuring you have plenty of rings on hand.

Product Details

This bulk pack includes 48 sets of Mahle OE Performance Piston Rings, designed for a 4.160-inch bore. Each set features a 1.5mm thick top ring made of plasma-moly steel, paired with a moly ring. These rings are crucial for sealing the combustion chamber, managing oil consumption, and transferring heat from the piston to the cylinder wall. Mahle is a well-known name in engine components, and this set is built for demanding applications where reliable performance is key.

The plasma-moly steel top ring offers improved durability and wear resistance compared to standard cast iron rings, helping to maintain a tight seal under high stress. The moly coating on the second ring further aids in reducing friction and wear, contributing to a longer ring and piston life. This bulk pack is ideal for engine builders or shops working on multiple performance builds or high-volume engine overhauls. Ensuring proper ring gap and installation is critical for optimal performance and longevity in any engine rebuild.

When rebuilding an engine, it's important to have all the necessary components ready. This set provides a substantial quantity of high-performance piston rings, suitable for a variety of performance engine projects. Always refer to your engine's specific service manual for correct installation procedures and ring gap specifications to ensure the best possible outcome for your build.
