Mahle MS 86.50mm Bore 1.2mm UCR 1.2mm LCR 2.8mm OCR Drop In (6cyl) Piston Rings (Set of 6)

If you're rebuilding the engine in a 6-cylinder vehicle and need to replace the piston rings, this set from Mahle is a well-built option. These rings are designed to fit pistons with an 86.50mm bore, which is a common size for many inline-six engines. Getting the right ring set is crucial for proper compression and oil control, and Mahle has a solid reputation for making reliable engine components.

This particular set features a 1.2mm top compression ring (UCR), a 1.2mm second compression ring (LCR), and a 2.8mm oil control ring (OCR). This combination is designed to provide a good balance of sealing performance and oil management. They are a drop-in replacement, meaning they are made to fit standard pistons of the specified bore size without needing any modifications, which can save you time and hassle during your rebuild.

Remember that these rings are not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual for correct installation procedures and ring gap specifications.
