Product Details
Mahle is known for making well-built engine components, and this bulk pack of 48 Napier THM-13 piston rings is no exception. These rings are designed for a 4.035-inch bore, making them a solid option for engine rebuilds where you need a consistent supply of high-performance rings.
The Napier hook design on the second ring helps to scrape oil from the cylinder walls, which can improve oil control and reduce blow-by. This helps ensure that your engine runs efficiently and lasts longer. The plain finish on these rings is standard for many performance applications, offering good sealing against the cylinder wall. This bulk pack is ideal for shops or builders who frequently work on engines requiring this specific bore size.
