Mahle Rings 4.1350 Bore Dia 1.2MM Edge Width Steel Plasma Moly Top Ring Moly Ring Set

When you're rebuilding the top end of your engine, getting the piston rings seated correctly is crucial for sealing and performance. This Mahle OE ring set is built for that job, featuring a 1.2mm edge width top ring with a steel plasma moly coating for durability and a moly ring for the second position. These rings are designed to fit a 4.1350 inch bore diameter, ensuring a proper seal against the cylinder wall.

Mahle has a long history of supplying parts for engine manufacturers, and this set reflects that experience. The plasma moly coating on the top ring helps it resist wear and maintain its sealing ability over time, even under demanding conditions. The moly second ring complements the top ring's function, contributing to a complete seal and helping to control oil consumption. This set is a solid option for anyone looking to restore their engine's compression and efficiency.
