What is the material of these piston rings?

These Mahle OE piston rings are constructed from grey iron. This material is chosen for its good wear resistance and thermal conductivity, which are important for engine performance and longevity.

What does 'second ring' mean in this context?

In a typical piston assembly, there are usually two compression rings and one oil control ring. The second ring is the lower of the two compression rings, located directly above the oil ring. It plays a crucial role in sealing combustion pressure and controlling oil.

Why is this a bulk pack of 48?

This is a bulk pack of 48 ring sets, making it suitable for engine builders or machine shops that work on multiple engines. It's particularly useful for V-type engines which require more sets of rings than inline engines.

Product Details

This is a bulk pack of 48 Mahle OE grey iron second ring sets. These rings are designed for a 3.5630 inch bore diameter and feature a 1.5mm edge width. They are a plain ring style, intended for use as the second compression ring in an engine's piston assembly. Mahle is a well-known name in engine components, and these rings are built to OE specifications, meaning they are made to fit and function just like the original parts your engine came with.

The grey iron construction offers good wear resistance and thermal conductivity, which are important for maintaining a good seal between the piston and cylinder wall. This helps to ensure proper compression, efficient combustion, and reduced oil consumption. Because this is a bulk pack of 48 sets, it's ideal for machine shops or engine builders who frequently work on multiple engines or larger V-type configurations that require many sets of rings. Ensure you check the specific engine application to confirm these rings are the correct size and type for your rebuild.
