Mahle Rings 4.0500 Bore Dia 3/16in Edge Width CP20 Oil Ring Low Tension Chrome Ring Set

When you're rebuilding an engine, getting the piston rings right is crucial for proper sealing and oil control. This Mahle OE CP20 low-tension chrome ring set is designed for a 4.0500 inch bore diameter, featuring a 3/16 inch edge width on the oil ring. Low-tension rings are often chosen for performance builds or when a specific factory specification calls for them, as they can reduce drag on the cylinder wall compared to higher-tension designs.

The chrome plating on the top ring offers good durability and helps it seat well against the cylinder wall. Mahle is a well-known name in engine components, and this set is built to meet the demands of an engine rebuild. Ensure you have the correct bore size for your application before ordering, as these are specific to a 4.0500 inch cylinder bore.
