Mahle Rings Performance Plasma Steel Top Ring 4.175in x 1.0MM .143in RW HVOF Moly Ring Set

The top ring in this Mahle set features a plasma-sprayed steel construction, applied using HVOF (High Velocity Oxygen Fuel) thermal spray technology. This advanced coating process creates a dense, well-bonded layer that stands up to the heat and stress of performance engines. The ring itself measures 4.175 inches in bore diameter with a 1.0mm thickness and a .143 inch radial width, designed for a precise fit in compatible pistons.

This ring set is built with performance in mind, utilizing a moly-filled top ring for improved sealing and reduced friction. The steel construction offers a strong and durable option for engines that demand more than standard components. Mahle is a well-known name in engine parts, and this set reflects their focus on providing reliable components for engine builds.
