Mahle Rings 4.563in Bore .043in 1/16in 3/16in Low Tension High Performance Ring Set Moly Ring Set

Mahle is known for making solid engine components, and this high-performance ring set is no exception. If you're rebuilding an engine and need a reliable set of piston rings, these are a great option. They're designed for a 4.563-inch bore and feature a low-tension design with moly face coatings, which helps them seat well and reduce friction.

The ring sizes are .043 inch for the top ring, 1/16 inch for the second ring, and 3/16 inch for the oil ring. This combination is common in many high-performance applications where efficient sealing and reduced oil consumption are key. The moly coating on the face of the top ring is a popular choice because it helps with initial break-in and provides a durable surface that works well with various cylinder wall finishes.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for installation procedures and recommended break-in processes.
