What does 'plain ring' mean for these piston rings?

A plain ring design means the ring is a solid piece of metal without any special coatings, such as molybdenum or chrome. This straightforward construction relies on precise manufacturing and material properties to create a seal.

Why is this a bulk pack of 48 sets?

This bulk pack is designed for professional engine builders or shops that frequently work on multiple engines requiring the same piston ring specifications. It offers a more economical way to stock up on a large quantity of rings.

What are the implications of this product not being CARB approved?

Product Details

This is a bulk pack of 48 sets of Mahle OE PC479 top piston rings. These rings are designed for a 4.160-inch bore diameter and feature a plain ring design, meaning they are a solid piece of metal without any special coatings or treatments, which is a common and reliable choice for many engine builds. Mahle is a well-known name in engine components, and these rings are intended for engine rebuilding applications where precision and durability are key. The 1/16 inch thickness is a standard size for many top compression rings, ensuring a good seal against the cylinder wall.

When you're rebuilding an engine, the piston rings are critical for proper compression, oil control, and heat transfer. These Mahle rings are made to OE specifications, meaning they are designed to meet or exceed the original equipment standards for fit and function. The plain ring design is straightforward and effective, relying on precise manufacturing tolerances to create a seal. This bulk pack is ideal for shops or builders who work on multiple engines of the same specification, offering a cost-effective way to stock up on essential components. Proper installation is crucial; ensure your cylinder bores are honed correctly and that the rings are seated properly to achieve optimal performance and longevity.

This particular set is not CARB approved and cannot be shipped to California. Always refer to your specific engine's service manual for detailed installation instructions and specifications to ensure a successful rebuild.
