Mahle Rings Perf Gas Nitride Steel 4.000 x .043 .157 RW Bulk Plain Ring Set (48 Qty Bulk Pack)

This bulk pack contains 48 Mahle OE Performance Gas Nitride Steel Piston Rings, designed for a 4.000-inch bore. These rings feature a nitride coating for improved durability and wear resistance, making them a solid option for performance gas engine builds. The ring set includes top compression rings and oil control rings, all manufactured to Mahle's well-known standards.

The nitride treatment on these rings helps them withstand the higher temperatures and pressures often found in performance applications. This process hardens the surface, reducing friction and extending the life of both the rings and the cylinder walls. Each ring is precisely manufactured to ensure a proper seal, which is critical for maintaining compression and preventing blow-by in your engine.

This bulk pack is ideal for shops or builders who frequently work on engines requiring this specific bore size and performance ring set. Ensure you check manufacturer specifications for proper installation and compatibility with your specific piston and cylinder head combination.
