Product Details
This Mahle oil ring support rail is made from a strong steel alloy, measuring 2mm thick. It's designed to fit pistons with bores between 4.125 and 4.165 inches. The primary job of this small but important part is to keep the oil control ring's expander in place, ensuring it maintains proper tension against the cylinder wall. Without good support, the oil ring can lose its seal, leading to increased oil consumption and potential cylinder wall scoring.
When you're rebuilding an engine, especially if you're going beyond a basic refresh, attention to detail on parts like this makes a big difference. This support rail is a well-built piece from Mahle, a name known for reliable engine components. It's a straightforward replacement part that fits right into the groove on your piston, working with the oil ring expander to maintain a consistent seal.
