About this part

Product Details

If you're rebuilding the top end of your engine, getting the right piston rings is crucial for sealing the combustion chamber. This Mahle OE ductile iron ring set is designed for a 4.075-inch bore, fitting many popular V8 applications. They are built to create a tight seal between the piston and cylinder wall, which is key for maintaining compression and preventing oil from entering the combustion chamber.

These rings are made from ductile iron, a strong material that can handle the heat and pressure inside the cylinder. The BT-18 design is a popular choice for performance builds because it offers a good balance of sealing capability and durability. You'll find that a well-sealed cylinder contributes to smoother engine operation and more consistent power delivery.

Keep in mind that this ring set is not CARB approved and cannot be shipped to California. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
