Mahle Rings 4.470in Bore Dia .017in Dykes PC479 Top Rings Plain Ring Set (48 Qty Bulk Pack)

Mahle OE Piston Rings are a bulk pack of 48 top rings designed for a 4.470-inch bore diameter. These rings feature a .017-inch Dykes design, which is a specific type of ring groove that helps to control oil consumption and blow-by. Mahle is a well-known name in engine components, and these rings are built to meet the demands of engine rebuilding and performance applications.

This particular set, part number 3010242B, is a plain ring set, meaning it's designed for the top compression ring position. The Dykes design is notable for its ability to create a tight seal against the cylinder wall, which is crucial for maintaining compression and preventing combustion gases from escaping into the crankcase. This helps to ensure efficient engine operation and can contribute to improved power and fuel economy when installed correctly. The bulk pack of 48 rings makes this a practical choice for shops or individuals working on multiple engines or performing extensive rebuilds.

When rebuilding an engine, the piston rings are a critical component that works directly with the cylinder walls to seal the combustion chamber. Ensuring you have the correct ring size and type is paramount for the longevity and performance of the engine. These Mahle rings are a solid option for those looking for reliable, OE-level components for their engine build. Please note that these rings are not CARB approved and cannot be shipped to California.
