What do these specific ring sizes (1.0mm, 1.2mm, 2.8mm) mean?

These numbers refer to the groove dimensions on the piston that the rings are designed to fit. The 1.0mm is for the top compression ring, the 1.2mm is for the second compression ring, and the 2.8mm is for the oil control ring. It's important to match these to your pistons.

Are these rings suitable for all engine rebuilds?

These rings are designed for specific piston and cylinder bore dimensions. While Manley Performance is a popular choice for many engine builds, you must verify that your pistons and bore size match these ring dimensions (1.0mm, 1.2mm, 2.8mm) before purchasing.

About this part

Product Details

When you're rebuilding the top end of your engine, getting the piston rings seated correctly is crucial for performance and longevity. These Manley Performance piston rings are designed to create a tight seal between your pistons and cylinder walls, which is essential for maintaining compression and preventing oil from entering the combustion chamber. A good seal means your engine will run more efficiently and last longer.

This set features a specific ring groove sizing: 1.0mm for the top ring, 1.2mm for the second ring, and 2.8mm for the oil ring. This sizing is common in many performance and stock rebuild applications. Manley is known for well-built engine components, and these rings are made to handle the demands of an engine rebuild. Proper installation is key to their function, so make sure you follow your engine's service manual for the correct procedure.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for installation details and ensure you have the correct ring set for your piston and bore size.
