Mahle Rings Pro Series Performance Ring Low Tension 4.125 Bore Moly Ring Set

If you're rebuilding the engine in your performance vehicle and need a solid set of piston rings, this Mahle Pro Series set is a great option. These rings are designed for a 4.125 inch bore, and they feature a low-tension design that works well in high-performance applications. The moly coating on the top ring helps reduce friction and wear, which is crucial for keeping your engine running smoothly under demanding conditions.

Mahle has been a trusted name in engine components for a long time, and this Pro Series set reflects that experience. The moly coating is applied to the top ring, providing a durable surface that can handle the heat and stress of performance engines. This coating also helps with initial break-in, ensuring a good seal between the piston and cylinder wall right from the start. It's important to note that these rings are not CARB approved and cannot be shipped to California.
