Mahle Rings 4.505in Bore Dia 1/16in PC479 Top Rings Plain Ring Set (48 Qty Bulk Pack)

When you're rebuilding an engine, especially for a high-performance application or a fleet of vehicles, getting the right piston rings is crucial for sealing the combustion chamber and managing oil. This bulk pack from Mahle OE gives you 48 sets of their PC479 top rings, designed for a 4.505-inch bore diameter. These are plain rings, meaning they don't have any special coatings or features beyond the basic, solid ring design that's been a workhorse in engine building for decades.

Mahle is a well-known name in the engine components world, and these rings are built to meet the demands of serious engine work. The 1/16-inch thickness for the top ring is a common specification, and these rings are made to fit precisely within that groove. Because this is a bulk pack of 48 sets, it's ideal for shops that do a lot of engine rebuilds or for manufacturers assembling multiple engines. You're getting a solid, reliable component from a trusted brand, ensuring good compression and oil control when installed correctly.

It's important to note that these rings are not CARB approved and cannot be shipped to California. Always refer to your specific engine's service manual for installation procedures and any other components you might need for a complete rebuild, such as pistons, bearings, and gaskets.
