Mahle Rings 3.9050in X 5/64in EW Grey Iron RBT Std Gap Second Ring Plain Ring Set (48 Qty Bulk Pack)

This is a bulk pack of 48 Mahle OE second ring sets, designed for engine rebuilding. Each ring measures 3.9050 inches in bore size with a 5/64 inch width and features a standard gap. These rings are made from grey iron, a solid material known for its wear resistance and ability to handle heat, making them a reliable choice for many engine applications. The RBT designation indicates a specific ring design, and the 'EW' likely refers to a specific coating or treatment for improved performance and longevity.

Mahle is a well-known name in engine components, and this set offers a practical solution for mechanics or engine builders who need a large quantity of high-quality second rings for multiple projects or a single large job. The grey iron construction means these rings will seat well against the cylinder wall and provide good oil control, which is crucial for engine health and performance. Because they are a standard gap ring, they offer broad compatibility across various engine builds where precise gap customization isn't the primary concern.

This bulk pack is ideal for shops or serious DIYers tackling multiple engine overhauls. Remember that these rings are not CARB approved and cannot be shipped to California.
