Product Details
This is a Mahle OE Piston Rings set, part number 3021224. These rings are designed for engine rebuilds where performance and durability are key. The set features a steel Napier 2nd ring, which is known for its ability to reduce oil consumption and prevent blow-by, helping to maintain consistent cylinder pressure.
The Napier hook design on the second ring helps to scrape oil from the cylinder wall on the downstroke, while the shape allows it to expand and seal effectively on the upstroke. This updated design contributes to improved engine efficiency and longevity. The rings are made from durable steel, built to withstand the rigors of regular engine operation.
