Mahle Rings Gas Nitride Steel Perf Top Comp 4.535in x .043in .170 RW Plain Ring Set (48 Qty Bulk Pk)

The gas nitride steel construction on these top compression piston rings is a key detail, offering improved durability and wear resistance compared to standard materials. Each ring measures 4.535 inches in bore size with a 0.043-inch thickness, designed for high-performance applications where sealing is critical. This bulk pack contains 48 sets, making it a practical choice for engine builders or shops working on multiple projects.

Mahle OE is known for producing well-built engine components, and these rings are no exception. The nitride treatment on the top ring surface helps to create a harder, more resilient layer that can withstand the higher temperatures and pressures found in performance engines. This advanced surface treatment contributes to a better seal between the piston and cylinder wall, which is essential for maximizing power output and efficiency. The precise manufacturing ensures these rings fit right into the piston grooves, minimizing the chance of blow-by and oil consumption.

When rebuilding or modifying an engine for performance, the piston rings are a crucial element for achieving optimal results. These Mahle rings are a solid option for those looking to ensure a strong seal and reliable operation. Please note that these rings are not CARB approved and cannot be shipped to California.
