Mahle Rings 4.380in Bore Dia .017in Dykes PC479 Top Rings Plain Ring Set

Mahle OE Piston Rings are designed for engine rebuilds where precise fit and reliable performance are key. This set features top rings with a .017 inch Dykes design, specifically made for a 4.380 inch bore diameter. Mahle is a well-known name in engine components, and these rings are built to meet the demands of a refreshed engine.

The .017 inch Dykes style on these top rings helps to create a strong seal against the cylinder wall. This is important for maintaining compression and preventing blow-by, which directly impacts how well your engine runs. They are a plain ring set, meaning they focus on the core function of sealing without added coatings or complex designs, making them a straightforward choice for many engine builds. Remember, these rings are not CARB approved and cannot be shipped to California.
