Mahle Rings Perf Plasma Steel Top Ring 4.305in x 1.0MM .143in RW HVOF Moly Ring Set (48 Qty Bulk Pk)

Mahle is a well-known name in the automotive industry, especially for their engine components. This particular product is a bulk pack of performance plasma steel top rings, designed for serious engine builds. These rings are built to handle the demands of high-performance applications, ensuring a solid seal between the piston and cylinder wall. The plasma-sprayed Moly coating on the top ring is a key feature, offering improved wear resistance and reduced friction, which is crucial for maintaining engine power and longevity under stress.

Each ring measures 4.305 inches in bore diameter and has a 1.0mm width with a 0.143-inch thickness. The RW (Right-angle Wall) design and HVOF (High-Velocity Oxygen Fuel) Moly coating are advanced features that contribute to their performance. This bulk pack contains 48 rings, making it suitable for engine builders or shops working on multiple engines or high-performance projects that require precise, reliable piston ring sets. The steel construction offers strength and durability, essential for maintaining compression and preventing blow-by in demanding conditions.

When rebuilding an engine, the piston rings are critical for sealing combustion pressure and controlling oil consumption. These Mahle rings are a solid option for those looking for robust components that can withstand higher cylinder pressures and temperatures. It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific build requirements and manufacturer guidelines when selecting piston rings.
