Mahle Rings 3.5640in Bore CP20 Std Tension 4.75MM Oil Ring Assembly Chrome Ring Set

This is a Mahle OE standard tension piston ring set, part number 3030598. It's designed for a 3.5640-inch bore and features a 4.75mm oil ring assembly with chrome rings. These rings are crucial for sealing the combustion chamber, controlling oil consumption, and transferring heat from the piston to the cylinder wall. The chrome plating on the top ring helps improve durability and wear resistance, especially in demanding engine conditions.

Mahle is a well-known name in engine components, and this set is built to meet OE specifications. The standard tension design is suitable for a wide range of engine rebuilds where optimal sealing and oil control are needed without requiring specialized high-performance tension. Proper installation is key to ensuring these rings perform as intended, maintaining compression and preventing excessive oil burn.
