Product Details
If you're rebuilding the top end of your engine, getting the piston rings seated just right is crucial for oil control and compression. These oil ring expanders from Mahle are designed to work with your oil control rings, helping them maintain proper tension against the cylinder wall. This ensures that oil is scraped effectively from the cylinder walls during the piston's downstroke, preventing it from entering the combustion chamber.
Mahle is a well-known name in engine components, and these expanders are built to standard tension specifications. They are made to fit a 4.145-inch bore size and are 3.0mm thick, which is a common size for many performance and rebuild applications. Proper installation of these expanders, along with the oil rings themselves, is key to a healthy, leak-free engine.
