Mahle Rings 4.0600 Bore Dia 3/16in Edge Width CP20 Oil Ring Std Tension Chrome Ring Set

These Mahle OE piston rings feature a 4.0600 inch bore diameter and a 3/16 inch edge width, designed for standard tension applications. The oil rings are finished with chrome, a material known for its durability and ability to reduce friction against the cylinder wall. This combination helps ensure a good seal between the piston and cylinder, which is crucial for efficient engine operation and preventing oil from entering the combustion chamber.

Mahle is a well-known name in engine components, and this set is built to meet the needs of a standard rebuild. The standard tension is suitable for a wide range of engine builds where extreme performance isn't the primary goal, focusing instead on reliable sealing and longevity. The chrome plating on the oil ring provides a hard, smooth surface that works well with various cylinder wall finishes.
