What is the purpose of the different ring sizes (1.5mm and 3mm)?

The 1.5mm top ring is the primary compression ring, designed to seal the combustion chamber. The 3mm oil ring controls oil flow to prevent it from entering the combustion chamber. These specific sizes are chosen for optimal performance in the Hemi 6.4L engine.

Are these rings suitable for a stock Hemi 6.4L rebuild?

Yes, these rings are designed for the 4.095-inch bore common in Hemi 6.4L engines and are made from premium steel for good sealing. They are a popular choice for engine rebuilds where reliable performance is desired.

About this part

Product Details

These Manley piston rings are made from premium steel, with a 1.5mm top ring and a 3mm oil ring, designed for a 4.095-inch bore. When you're rebuilding the top end of your Chrysler Hemi 6.4L engine, getting the right piston rings is crucial for proper sealing and performance. This set is built to handle the demands of these powerful engines.

Manley Performance uses quality steel for these rings, which helps ensure they can maintain a good seal against the cylinder wall, even under high heat and pressure. The specific ring thicknesses – 1.5mm for the top compression ring and 3mm for the oil control ring – are chosen to work effectively with the pistons and cylinder bore dimensions for this application. This attention to detail in material and sizing helps contribute to improved engine efficiency and longevity.

Keep in mind that this ring set is not CARB approved and cannot be shipped to California. If you're working on a Hemi 6.4L, these rings are a solid option for a rebuild where reliable sealing is a priority.
