What does the '0.030' mean in the part number?

The '0.030' indicates that these piston rings are 0.030 inches larger in diameter than the standard size. This is used when the engine's cylinders have been bored out to a larger size during a rebuild to ensure a proper fit.

What is the benefit of reducing friction with these rings?

Reducing friction between the piston and cylinder wall helps the engine run more efficiently, can improve fuel economy slightly, and contributes to a longer overall service life by minimizing wear.

Are these rings suitable for all engine rebuilds?

This specific set is designed for certain Buick, Dodge, and Plymouth V8 engines from the late 1960s and early 1970s. It's crucial to verify that your engine model and bore size match the specifications for this ring set.

Product Details

If you're rebuilding the engine in a classic Buick, Dodge, or Plymouth, getting the right piston rings is key to a healthy rebuild. These Mahle OE plain ring sets are designed to fit specific V8 engines from the late 60s and early 70s, like the Buick 400, Dodge 340, and Plymouth 340. They help ensure your engine seals properly, minimizing oil burning and maximizing compression for reliable performance.

Mahle is known for making technically advanced rings that meet original equipment requirements. These particular rings are 0.030 inch undersize, which is important if your cylinders have been bored out to that size during the rebuild process. They're built to reduce friction between the piston and cylinder wall, which not only helps with engine efficiency but also contributes to a longer service life for your freshly rebuilt engine.

This set is a solid option for many popular muscle car engines of the era. Remember to check your cylinder bore size to confirm if the 0.030 inch undersize is correct for your specific engine build.
