Mahle Rings 4.3900 Bore Dia 3/16in Edge Width CP20 Oil Ring Std Tension Chrome Ring Set

Mahle is known for making reliable engine components, and these piston rings are no exception. This set is designed for a 4.3900 inch bore diameter and features a CP20 oil ring with standard tension and a chrome face. They are a solid choice for rebuilding or refreshing your engine.

The chrome face on the oil ring helps it stand up to wear, which is important for maintaining a good seal between the piston and cylinder wall. This helps keep oil out of the combustion chamber and combustion pressure in the cylinder, both of which are critical for engine performance and longevity. This set is designed for a direct fit, making installation straightforward when you're working on your engine rebuild.
