The piston uses the latest technology and design utilizing a racing slipper skirt vs. a conventional barrel skirt design of other stock pistons. This piston uses an aluminum alloy with high silicon for a lower thermal expansion coefficient, allowing tighter tolerance for superior performance and longevity. The low slipper skirt design also allows more clearance in the rotating assembly for larger stroke crankshafts. This piston has a shorter compression height due to the pin's location and using a smaller diameter wrist pin allows the use of a longer rod while reducing weight in the rotating assembly.
