What is the primary function of piston rings?

Piston rings have a few key jobs. They seal the combustion chamber to maintain compression and power, regulate oil consumption by scraping oil off the cylinder walls, and help transfer heat from the piston to the cylinder wall.

Are these rings suitable for all engine rebuilds?

These rings are specifically for engines with a 4.030 inch bore. Proper ring gapping is also crucial for performance and longevity, so always follow the manufacturer's recommended procedures during installation.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these piston rings are a solid example of that. If you're rebuilding an engine with a 4.030 inch bore, these rings are designed to fit right and help your engine run smoothly. They play a critical role in sealing the combustion chamber, which is key for getting good power and keeping oil out of the exhaust.

These rings are made with good materials to handle the heat and pressure inside your engine. The specific dimensions, 1/16 inch for the top ring and 3/16 inch for the oil ring, are standard sizes for many performance and rebuild applications. Getting the right ring tension and seal is important for the longevity and performance of your rebuilt engine.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper ring gapping and seating procedures during your engine build.
