If you're rebuilding a performance gasoline engine and need a bulk supply of piston rings, this Mahle OE set is a solid option. These rings are designed for a 4.030 inch bore and feature a .043 inch thickness for the top and second rings, with a .157 inch oil ring. The nitride coating on the top ring is a notable feature that helps improve wear resistance and durability, especially in performance applications where engines are pushed harder.

The steel construction offers good strength, and the nitride treatment adds an extra layer of protection against friction and heat. This bulk pack contains 48 sets, making it a practical choice for engine builders or shops that handle multiple builds of the same engine configuration. Having a ready supply ensures you can keep your projects moving without waiting for parts.
