Mahle Rings Perf 3.6299in x 1.2MM Steel Plasma Moly Top Comp Ring .143in RW Ring Set (48 Qty Bulk)

Mahle OE Piston Ring Set 3011252B is a bulk set of 48 top compression rings, each measuring 3.6299 inches in diameter with a 1.2mm thickness. These rings are constructed from steel with a plasma-moly coating, a well-known combination for durability and performance in high-stress engine applications. The plasma-moly surface treatment helps reduce friction and wear, which is crucial for maintaining optimal sealing between the piston and cylinder wall under demanding conditions.

This set is designed for engine rebuilding projects where multiple engines or a high volume of components are being serviced. The steel construction offers solid strength, while the plasma-moly coating provides an improved wear surface that can withstand higher temperatures and pressures compared to plain cast iron rings. This combination helps ensure a good seal, which is essential for efficient combustion, proper oil control, and overall engine longevity. When installing, pay close attention to the ring gap and orientation to ensure proper function and prevent damage.

This bulk pack of 48 rings is a practical choice for machine shops or engine builders working on a significant number of engines that require this specific ring size and specification. It ensures you have enough high-performance rings on hand for your project. Please note that this part is not CARB approved and cannot be shipped to California.
