What does 'plain ring' mean for a top ring?

A plain top ring is a solid, unadorned ring without any special coatings or complex shapes. Its sealing ability comes from precise manufacturing and the material it's made from, often chosen for durability in various engine conditions.

Why would I need a bulk pack of 48 ring sets?

A bulk pack is ideal for professional engine builders or repair shops that frequently work on the same engine type. It ensures you have enough sets on hand for multiple projects, potentially offering a cost saving over individual sets.

What is the significance of the 4.130-inch bore diameter?

The 4.130-inch bore diameter is a specific measurement that must match the cylinder bore of your engine for proper fitment and sealing. This size is common in certain performance or heavy-duty engine applications.

Product Details

These Mahle OE Piston Rings are built with a 4.130-inch bore diameter and a 1/16-inch top ring specification, which is a common size for many performance and heavy-duty engine builds. This bulk pack contains 48 sets of rings, making it a practical choice for shops that frequently service a particular engine type or for engine builders working on multiple projects. Mahle is a well-known name in the automotive industry, recognized for producing reliable engine components that meet original equipment standards.

The PC479 top ring design is a plain ring, meaning it's a solid, unadorned ring that relies on its material and precise manufacturing for sealing. This type of ring is often chosen for its durability and ability to maintain a strong seal under demanding conditions. When rebuilding an engine, selecting the right piston rings is critical for proper compression, oil control, and overall engine longevity. These Mahle rings are designed to fit right and perform as expected, helping to ensure your engine runs smoothly and efficiently after the rebuild.

Because these rings are not CARB approved, they cannot be shipped to California. If you are outside of California and working on an engine that requires this specific bore size and ring configuration, this bulk pack offers a cost-effective solution for multiple builds. Always refer to your specific engine's service manual for detailed installation instructions and specifications to ensure a proper rebuild.
