PowerPack 2618 Alloy Forged Piston Set with 20mm Pins

Mahle Powerpack pistons provide improvements in strength over OEM pistons without some of the sacrifices sometimes found in other forged pistons. They are precision forged from 2618 alloy, making them very strong. These pistons feature forged side reliefs and a slipper skirt design, which reduces weight and friction. The ultra-flat ring grooves promote excellent ring seal and minimize micro-welding during break-in. Each set includes Mahle's exclusive Grafal skirt coating, which offers anti-friction properties and impact absorption, reducing piston noise and skirt stresses. The top ring grooves are hard anodized to prevent deformation in extreme duty applications. Mahle PowerPack Pistons are an excellent choice for those seeking increased strength while maintaining a lightweight piston with an OEM fit and finish. They feature 82.5mm bore, 92.8mm stroke, and a 9.3:1 compression ratio. These pistons utilize 20mm wrist pins, requiring a set of rods with matching 20mm pins. The set comes complete with rings and pins.
