About this part

Product Details

When you're rebuilding the bottom end of your engine, getting the piston rings seated just right is critical for oil control and compression. These Mahle oil ring expanders are designed to work with your oil control rings, ensuring they maintain proper tension against the cylinder wall. They are a standard tension type, meaning they offer a balanced approach to sealing without excessive drag.

Mahle is a well-known name in engine components, and these expanders are built to meet the demands of an engine rebuild. They are made to the correct size, 4.135 inches in diameter with a 3.0mm width, to fit specific oil ring configurations. Proper installation of these expanders is key to preventing oil from entering the combustion chamber and ensuring your engine runs cleanly.
