What is the purpose of moly coating on piston rings?

The moly coating on these Mahle piston rings helps with the initial break-in process by providing a durable, low-friction surface. This coating also contributes to a longer service life for the rings and the cylinder walls.

Why is it important to minimize oil consumption?

Minimizing oil consumption is important for engine health and performance. It prevents excess oil from entering the combustion chamber, which can lead to fouling of spark plugs, carbon buildup on pistons and valves, and reduced engine efficiency.

What does the '.020' in the part number signify?

The '.020' in the part number indicates that this is a 0.020 inch undersize piston ring set. This sizing is typically used when the engine cylinders have been honed or bored out to a slightly larger diameter during an engine rebuild.

Product Details

This is a Mahle OE Moly Piston Ring Set for your 1986-1992 Ford Ranger, Bronco II, or Merkur Scorpio equipped with the 2.9L engine. These rings are designed to work with your pistons to create a seal between the piston and cylinder wall, which is crucial for proper engine compression and preventing oil from entering the combustion chamber.

Mahle OE rings are built to meet the demanding requirements of original equipment manufacturers. They focus on reducing internal engine friction, which can help improve efficiency and potentially extend the life of your engine. Minimizing oil consumption is another key benefit, helping to keep your oil levels stable and reducing the need for frequent top-offs. The moly coating on these rings also helps with initial break-in and provides a durable surface for long service life.

This set is specifically sized at 0.020 inches undersize, which is important to note if you are rebuilding or re-ringing your engine. Always ensure you have the correct piston and cylinder wall preparation before installation to get the best performance and longevity from these rings.
