Product Details
When you're rebuilding the top end of your engine, getting the piston rings seated right is key to good compression and oil control. These Mahle Performance Steel Napier rings are a solid choice for that job. They're made with a steel Napier hook design, which helps them seal well against the cylinder wall and manage oil effectively, especially in performance applications where the engine is working harder.
The THM-13 set is designed for a 4.130 inch bore, with a standard .043 inch top ring and .135 inch oil ring groove. Mahle is a well-known name in engine components, and these rings are built to hold up. They're a direct replacement for many applications, making the installation process straightforward if you're already inside the engine.
