What is the purpose of the different ring thicknesses?

The different ring thicknesses are designed for specific sealing and oil control functions. The thinner top ring (1.2mm) helps create a tighter seal for compression, while the thicker second ring (3.0mm) assists in oil control and combustion chamber sealing.

Are these rings suitable for a stock or modified engine?

This ring set is built for the Gen 3 Coyote engine, which is often used in both stock and modified applications. The steel top ring offers good performance characteristics for various builds.

What does 'Not CARB approved' mean for buyers?

This means the product does not meet the emissions standards set by the California Air Resources Board (CARB). As a result, it cannot be legally shipped to or installed on vehicles registered in California.

Product Details

If you're rebuilding the engine in your 2018 or newer Gen 3 Coyote Mustang, a solid set of piston rings is crucial for proper compression and oil control. This set from Manley Performance is built for that specific application, featuring a 3.672-inch bore size and a 1.2mm thick top ring designed to seal tightly against the cylinder wall.

Manley has a reputation for making well-built internal engine components, and this ring set is no exception. The top ring is made of steel, which offers good wear resistance and can handle the heat generated in performance applications. The overall ring package includes a 1.2mm top ring, a 3.0mm second ring, and an oil ring, all designed to work together to ensure your engine runs efficiently and reliably. This set is for a complete set of 8 cylinders.

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 and seating procedures during your engine build.
