Mahle Original piston ring sets are designed to be installer-friendly. They are pre-lapped to seat immediately, virtually eliminating break-in time. Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application. The compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact. The CP-20 oil ring assemblies feature a 20 degree ear angle, an exclusive feature that provides the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drain back. Mahle Original piston ring sets provide unmatched quality and ease of installation, making them the rings of choice for today's engine builders.

Hastings Claimer Series Performance piston ring sets are for builders wanting value without sacrificing precision and performance. They start with top rings made from proprietary shell-mold cast iron with plasma moly impact-resistant alloy, providing a hard, yet lubricating, low-friction structure. The plasma moly coating improves wear resistance, reduces scuffing, traps lubricating oil, and is compatible with a wide range of cylinder bore materials. The 2nd rings are manganese phosphate coated. Claimer moly top rings are torsional positive twist and the 2nd rings are torsional reverse-twist taper face. Completing the set of Moly Claimer Performance rings are Hastings Flex-Vent oil rings that minimize friction, improve flexibility, and provide high-rpm oil control.
