About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these steel top piston rings are a great example of that. If you're rebuilding the engine in your Ford 5.0L DOHC (4 Valve) vehicle, especially for a performance application, these rings are designed to handle the demands. They're made from steel, which offers good durability and wear resistance for the piston crown.

These rings are specifically sized for a 3.630in to 3.635in bore, ensuring a proper seal within the cylinder. A good seal is crucial for maintaining compression, controlling oil consumption, and getting the most power out of your engine. The dome design on these top rings is intended to work with specific piston types to optimize combustion chamber shape and efficiency.

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 gap setting and installation procedures to ensure optimal performance and longevity.
