Mahle Rings Perf Oil Ring 4.720in x 2.0MM .129in RW GNS NHRA Pro Stock Plain Ring Set (48 Qty Bulk)

Mahle OE is a well-known name in the performance engine parts world, and this bulk set of NHRA Pro Stock oil rings is a prime example of their commitment to racing. These rings are specifically designed for the high demands of Pro Stock racing, meaning they're built to handle extreme conditions and deliver consistent performance when you need it most. The 4.720-inch diameter and 2.0mm thickness are standard for many high-performance applications, and the .129-inch rail width ensures a good seal.

This set comes with 48 rings, making it a bulk option suitable for engine builders or teams that go through a significant number of engines. The GNS NHRA Pro Stock designation tells you these are not your average oil rings; they are engineered for the specific requirements of that class of racing, focusing on durability and optimal oil control under intense stress. While they are built for performance, it's important to note they are not CARB approved and cannot be shipped to California.
