What does the 0.040 size mean for my engine?

The 0.040 size indicates these rings are 0.040 inches larger in diameter than standard rings. This is typically used when engine cylinders have been bored out to a larger size to accommodate wear or to increase displacement.

Why are Mahle rings considered advanced?

Mahle focuses on reducing friction and minimizing oil consumption, which are key factors for modern engine efficiency and longevity. Their design aims to provide a better seal and longer service life compared to basic replacement rings.

Are these rings compatible with all MaxxForce 7 engines from 2011 onwards?

These rings are designed for Navistar MaxxForce 7 engines from 2011 and newer. It's always best to confirm the specific part number and size requirements with your vehicle's service manual before purchasing.

Product Details

If you're rebuilding the top end of your Navistar MaxxForce 7 engine from 2011 and newer, a fresh set of Mahle piston rings is a smart move. These aren't just any rings; they're built to meet the demanding requirements of modern engines, focusing on reducing friction and minimizing oil burning. Getting this right means your engine will run smoother and last longer.

Mahle engineers these rings with a focus on advanced technology. They work to cut down on internal friction, which not only helps the engine perform better but also contributes to better fuel efficiency. Plus, they're designed to seal the combustion chamber effectively, which is key to preventing oil from getting into the combustion process and being burned. This attention to detail helps ensure a longer service life for your engine components.

This particular set is sized 0.040 inch larger than standard, which is important to know if you're replacing worn pistons or have had the cylinders bored out. Make sure to check your service manual for the correct sizing for your specific rebuild project.
