Mahle Rings 4.040in Bore Dia 4.0MM Edge Width CP20 Oil Ring Std Tension Chrome Ring Set

Mahle is known for making solid engine components, and this piston ring set is no different. This set is designed for a 4.040 inch bore diameter and features a 4.0MM edge width oil ring with standard tension. The chrome plating on the rings helps them hold up to the demands of the engine and provides a good seal against the cylinder wall.

These rings are a standard tension set, meaning they offer a good balance of sealing ability and reduced drag on the piston. The chrome ring surface is a popular choice because it's well-built and resists wear, helping to ensure a good seal between the piston and the cylinder wall for a long time. If you're rebuilding an engine and need a reliable set of piston rings, this Mahle OE set is a solid option.
