Mahle Rings Perf Plasma Steel Top Ring 4.185in x 1.0MM .143in RW HVOF Moly Ring Set (48 Qty Bulk Pk)

Mahle is a well-known name in the automotive industry, often recognized for their OE (Original Equipment) quality components. This particular product, the Mahle Rings Perf Plasma Steel Top Ring set, is built for performance applications where durability and precise sealing are critical. These rings are designed to fit a 4.185-inch bore, with a specific 1.0mm top ring thickness and a .143-inch ring groove width, making them suitable for many performance engine builds.

The top rings feature a plasma-moly coating applied using HVOF (High Velocity Oxygen Fuel) thermal spray technology. This advanced coating process creates a very dense, well-bonded layer that offers excellent wear resistance and reduced friction. This is important for high-performance engines that experience higher cylinder pressures and temperatures. The steel construction of the rings themselves also contributes to their strength and ability to maintain sealing under demanding conditions. This bulk pack contains 48 rings, intended for engine builders or shops working on multiple performance engines.

It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to your specific engine build requirements and manufacturer's installation guidelines to ensure proper fitment and performance.
