Mahle Rings 4.3900in X 5/64in Cast Claimer Top Compression Ring Plain Ring Set (48 Qty Bulk Pack)

Mahle is known for making well-built engine components, and this set of 48 cast claimer top compression rings is no exception. These rings are designed for a 4.3900-inch bore size and feature a 5/64-inch top compression ring profile, a common size for many engine builds. They are a plain ring design, meaning they don't have any special coatings or treatments, making them a solid option for a wide range of applications where a reliable seal is needed.

This bulk pack is ideal for shops or builders working on multiple engines or those who prefer to have extra parts on hand. The cast construction offers good durability for everyday use, and the precise sizing ensures they will fit right into the piston grooves. When you're rebuilding an engine, getting the piston ring seal right is crucial for compression and oil control, and Mahle's reputation in the OE space means you can trust these rings to perform as expected.
