Mahle Rings 4.1400in Bore Dia 1/16in Edge Width THG Gray Iron Second Ring Plain Ring Set

If you're rebuilding the engine in your vehicle, getting the right piston rings is a critical step for proper sealing and performance. This set from Mahle OE is designed for a 4.1400 inch bore diameter and features a 1/16 inch edge width on the second ring, which is made from gray iron. This material choice is common for second compression rings because it offers good wear resistance and can handle the heat and pressure found in the combustion chamber.

Mahle is a well-known name in engine components, and these rings are built to OE specifications. The plain ring design for the second ring is a straightforward and reliable choice for many engine builds. Ensuring a good seal between the piston and cylinder wall is key to maintaining compression, preventing oil from entering the combustion chamber, and getting the most power out of your engine.

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 detailed installation instructions and any other components you might need for your engine rebuild.
