Mahle Rings 4.505in Bore Dia 1/16in PC479 Top Rings Plain Ring Set

These Mahle OE top rings are made with a 1/16 inch thickness, designed for a 4.505 inch bore diameter. This specific sizing and material choice is crucial for creating a proper seal between the piston and the cylinder wall. A good seal means your engine can build and maintain compression effectively, which is key for smooth operation and power delivery.

Mahle is a well-known name in engine components, and these rings are built to meet the demands of engine rebuilding. The PC479 designation indicates a specific design intended for reliable performance. When you're putting an engine back together, getting the piston rings right is one of those details that makes a big difference in how the whole thing runs. They are designed to handle the heat and pressure inside the combustion chamber, helping to prevent blow-by and oil consumption.

Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for installation procedures and any other components you might need for your engine rebuild.
