Mahle Rings Int Trac 152 CID 2.5L 4 cyl 3.375 in 85.7mm OverBore Conversion Sleeve Assy Ring Set

This is a Mahle OE Piston Ring Set, part number S41038. This set is designed for an overbore conversion, meaning it's intended for engines that have had their cylinders bored out to a larger diameter than stock. The rings are sized for a 3.375 inch (85.7mm) bore, suitable for 152 cubic inch (2.5L) 4-cylinder engines.

Mahle is a well-known name in engine components, and this ring set is built to meet the needs of an engine rebuild where the cylinders have been modified. Proper ring seal is crucial for engine performance and longevity, especially in an overbored application where tolerances are tighter and heat management is key. This set is designed to provide a solid seal between the piston and the cylinder wall, helping to maintain compression and control oil consumption.
