What material are these piston rings made from?

These Mahle OE piston rings are made from grey iron. Grey iron is a common material for piston rings due to its good wear resistance and thermal conductivity, which helps manage heat within the cylinder.

What does 'standard gap' mean for these rings?

Standard gap refers to the typical end gap size specified by the original equipment manufacturer for a given engine. It ensures the ring can expand properly with heat without binding in the cylinder bore, while still maintaining a good seal.

What is the advantage of buying a bulk pack of 48 ring sets?

A bulk pack of 48 ring sets is ideal for engine builders or shops that work on multiple engines. It provides a cost-effective way to stock up on essential components for various rebuild projects.

Product Details

This bulk pack includes 48 Mahle OE standard gap second ring plain ring sets. Each set is designed for a 3.7960-inch bore and features a 5/64-inch width. These rings are constructed from grey iron, a well-known material for its durability and wear resistance in engine components.

Mahle OE rings are a popular choice for engine rebuilds because they meet the original equipment specifications for fit and function. The grey iron material offers good thermal conductivity and is known for its ability to handle the stresses of combustion. This specific set is for the second ring position, which plays a crucial role in sealing the combustion chamber and controlling oil consumption. The standard gap ensures proper fitment in most applications where the cylinder bore is within specification.

This is a bulk pack, meaning you get 48 individual ring sets, making it a practical option for shops or individuals working on multiple engines or performing extensive rebuilds. Please note that these rings are not CARB approved and cannot be shipped to California.
