Mahle Rings Performance Oil Ring Assembly 4.165in x 2.0MM .113in RW Low Tension Chrome Ring Set

This is a Mahle OE Performance Oil Ring Assembly, part number 3030839. It's designed for engines with a 4.165-inch bore and features a low-tension, 2.0mm x 2.0mm x 3.0mm ring configuration with a chrome face for improved durability and performance.

These rings are a popular choice for builders looking for a well-built oil control solution. The low-tension design helps reduce drag on the cylinder wall, which can contribute to improved engine efficiency and a bit more power. The chrome plating on the oil ring face offers good wear resistance, helping it maintain its seal over time, especially in performance applications where engines are pushed a little harder.

When installing these rings, pay close attention to the ring gap specifications recommended by your engine builder or the Mahle OE documentation. Proper ring gap is crucial for sealing and preventing oil consumption. Remember that this part is not CARB approved and cannot be shipped to California.
