Mahle Rings Performance Plasma Moly Steel Top Compression Ring 4.615 x 1.0MM .143 RW Moly Ring Set

Mahle OE offers this performance plasma moly steel top compression ring set, designed for engines needing a reliable and durable ring for demanding applications. This set features rings with a 4.615 inch bore size and a 1.0mm thickness, with a .143 inch ring width. The plasma moly coating on these steel rings is known for its ability to reduce friction and wear, helping to maintain a strong seal between the piston and cylinder wall.

These rings are a well-built option for engine rebuilds where performance and longevity are key. The plasma moly surface treatment is a notable upgrade over standard cast iron rings, offering improved resistance to scuffing and heat. This helps ensure consistent compression and efficient oil control, contributing to overall engine health and power output. When installing, ensure the cylinder walls are properly honed and clean for optimal ring seating and performance.
