What does the '+.005' mean for these piston rings?

The '+.005' indicates that these rings are designed for a cylinder bore that is five-thousandths of an inch larger than the standard size. This is common during engine rebuilding when cylinders may have been honed or bored out.

What is the benefit of plasma moly coating on the top ring?

Plasma moly coating on the top piston ring helps to reduce friction and improve wear resistance. This can lead to a longer lifespan for the ring and the cylinder wall, as well as potentially improved engine performance.

Are these rings suitable for all engine types?

These rings are specifically designed for a 4.600 inch bore with a +.005 inch oversize. While Mahle is a reputable brand, you must confirm that this specific size and configuration matches your engine's requirements for a proper rebuild.

Product Details

This is a Mahle OE Moly Ring Set, part number 3150142.005. It's designed for a 4.600 inch bore and is an oversize set, specifically +.005 inches. The ring configuration features 1/16 inch for the top and second rings, with a 3.0mm oil ring. These are low tension rings with plasma moly coating on the top ring for improved durability and performance.

Mahle is a well-known name in engine components, and this set is built with ductile iron for the second ring and plasma moly for the top ring. This combination helps ensure a good seal against the cylinder wall, which is crucial for proper engine function. The low tension design can also contribute to reduced friction, potentially improving efficiency. This set is intended for engine rebuilds where precise fitment and reliable sealing are important.

Please note 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.
