The second ring in this set features a plain design, which is a common and reliable choice for many engine rebuilds.

Mahle has a solid reputation for making well-built engine components, and these rings are no exception. They are designed to create a good seal between the piston and cylinder wall, which is crucial for maintaining compression, controlling oil consumption, and ensuring efficient combustion. The grey iron construction helps them stand up to the rigors of engine operation.

Keep in mind that these rings are not CARB approved and cannot be shipped to California. Always refer to your engine's specific service manual for proper installation procedures and ring gap specifications.
