About this part

Product Details

This is a bulk pack of Mahle OE Performance Steel Piston Rings, specifically the THM-13 Napier style. These rings are designed for a 4.195-inch bore and come in a pack of 48, making them suitable for engine rebuilding shops or projects requiring multiple sets. The Napier hook design on the second ring helps to scrape oil from the cylinder wall, which can improve oil control and reduce blow-by.

Built with durable steel, these rings are made to withstand the rigors of engine operation. The specific dimensions are 1.5mm for the top ring, 1.5mm for the second ring, and 0.150 inches for the oil control ring. This configuration is chosen for its ability to provide a solid seal and manage oil effectively in a variety of performance applications.

Because this is a bulk pack, it's a practical choice for those working on multiple engines or needing spares. Please note that these rings are not CARB approved and cannot be shipped to California.
