What is the primary function of these piston rings?

These piston rings serve a few key functions: they seal the combustion chamber to maintain compression, regulate oil consumption by scraping excess oil from the cylinder walls, and help transfer heat from the piston to the cylinder wall. This set is designed with specific dimensions for optimal performance.

Are these rings suitable for all engine builds?

These rings are designed for specific piston bore sizes and ring groove dimensions. It's important to verify that your pistons are designed for a 4.030 inch bore and have the correct groove dimensions (0.043 inch for compression rings and 3mm for the oil ring) before purchasing.

What does 'Not CARB approved' mean?

CARB (California Air Resources Board) approval means a part meets specific emissions standards for use in California. Since these rings are not CARB approved, they cannot be legally sold or shipped to California due to emissions regulations.

About this part

Product Details

These Manley Performance piston rings are built with a 0.043 inch thickness for the compression rings and a 3mm oil ring. This specific sizing is crucial for achieving a proper seal between the piston and cylinder wall, which directly impacts engine performance and efficiency. When you're rebuilding an engine, getting the right ring dimensions is key to ensuring the cylinders hold compression effectively and oil stays where it belongs.

Manley is known for making well-built internal engine components, and these rings are no exception. They are designed to handle the demands of performance engines, offering a solid option for anyone looking to refresh their engine's internals. The precise manufacturing ensures they fit right into the piston grooves, making installation straightforward for someone familiar with engine assembly. Proper installation is vital for these rings to perform as intended, helping to reduce blow-by and oil consumption.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your specific engine build requirements and manufacturer recommendations to ensure these are the correct rings for your application.
