About this part

Product Details

The 1.5mm Napier hook on the top ring of this Mahle THM-13 set is a key design choice for improved oil control. This unique shape helps to scrape oil from the cylinder wall more effectively as the piston moves down, reducing oil consumption and blow-by. This bulk pack contains 48 sets, making it a solid option for shops or builders working on multiple engines that require a 4.005-inch bore size.

Mahle is known for well-built engine components, and these piston rings are no exception. They are constructed from durable materials designed to withstand the rigors of engine operation. The plain finish on these rings is a straightforward approach that focuses on reliable performance. When you're rebuilding an engine, the piston rings are critical for sealing the combustion chamber and managing oil, and this set from Mahle OE offers a practical solution for many applications.
