Mahle Rings Performance Napier THM-13 4.185 x .043 .135in RW Plain Ring Set (48 Qty Bulk Pack)

If you're rebuilding an engine, getting the piston rings right is a critical step for sealing the combustion chamber and managing oil. This Mahle OE THM-13 ring set is designed for that purpose, offering a well-built solution for your project. They feature a Napier hook design on the second ring, which helps to scrape oil off the cylinder wall more effectively, preventing it from entering the combustion chamber and contributing to a cleaner burn and better performance.

This bulk pack contains 48 sets of rings, making it a practical choice for shops or for those undertaking multiple engine builds. The rings are precision-made to fit a 4.185-inch bore with a standard thickness for the top ring and a .135-inch thickness for the oil control ring. Mahle is a well-known name in engine components, and these rings reflect their commitment to producing reliable parts that perform as expected during engine assembly and break-in.
