Mahle Rings Gas Nitride Steel Perf Top Comp 4.505in x .043in .170 RW Plain Ring Set (48 Qty Bulk Pk)

These Mahle OE piston rings feature a gas nitride steel construction for the top compression ring, a material choice that stands up well to the heat and pressure found in performance engines. The top compression ring measures 4.505 inches in bore diameter and is 0.043 inches thick, with a 0.170 inch ring wall. This specific design is intended for applications where improved sealing and durability are key, helping to maintain cylinder pressure and prevent blow-by.

Mahle is a well-known name in engine components, and this bulk pack of 48 ring sets is geared towards engine builders or shops working on multiple performance builds. The nitride treatment on the steel top ring is a notable detail; it hardens the surface, making it more resistant to wear and scuffing, which is crucial for longevity, especially when paired with performance camshafts or higher boost levels. This attention to material and surface treatment helps ensure a solid seal between the piston and cylinder wall, contributing to efficient combustion and consistent power delivery.

When rebuilding or modifying an engine, the piston rings are a critical component for sealing the combustion chamber. This set from Mahle OE is designed to meet the demands of performance applications, offering a well-built solution for engine builders looking for reliable components. Please note that these rings are not CARB approved and cannot be shipped to California.
