A shorter, narrower ring is more conformable, allowing it to maintain increased and more consistent contact with the ring groove floor and cylinder wall, resulting in greatly improved combustion seal and oil control.
MAHLE Motorsports has built a reputation for bringing racers leading-edge design and technology and continues to do so with the latest in innovations and racing advancements. More than a decade ago, MAHLE’s PowerPak piston assemblies were introduced with ring sets sized as much as 24 percent smaller in both height and width than conventional piston rings. A shorter, narrower ring is more conformable, allowing it to maintain increased and more consistent contact with the ring groove floor and cylinder wall, resulting in greatly improved combustion seal and oil control. Additionally, there is a notable reduction in frictional drag and weight.
