What does a 1/16in top ring signify?

A 1/16-inch top ring refers to the thickness of the piston ring. This is a common and standard size for many gasoline and some diesel engines, ensuring a proper seal against the cylinder wall when the piston is at the top of its stroke.

Are these rings suitable for all engine rebuilds?

These rings are designed for engines with a 4.535-inch bore and feature a plain top ring design. While this is a common configuration, always verify that this specific ring size and type match your engine's specifications before purchasing.

Can these rings be shipped to California?

No, these piston rings are not CARB approved and cannot be shipped to California.

Product Details

If you're rebuilding the top end of your engine, getting the right piston rings is crucial for sealing combustion pressure and controlling oil. This set from Mahle OE is designed for a 4.535-inch bore diameter and features a 1/16-inch top ring, a common size for many gasoline and some diesel applications. Mahle is a well-known name in engine components, and these rings are built to meet the demands of a freshly rebuilt engine.

These are plain top rings, meaning they have a simple, flat face. This design is effective for sealing and is often found in many factory engine builds. The 1/16-inch thickness is a standard dimension that ensures a good fit within the piston groove, helping to maintain proper tension against the cylinder wall. Proper ring tension is key to preventing blow-by and ensuring the engine runs efficiently.

When installing these rings, make sure your cylinder walls are properly honed to the correct cross-hatch pattern. This pattern helps the rings seat correctly and ensures they maintain their seal over time. Remember that this part cannot be shipped to California due to CARB regulations.
