Slipper Skirt Style Forgings: strong, lightweight, low drag forging superior to the traditional full round design.
Phosphate Coating: helps prevent microwelding in the ring grooves and pin galling.
Grafal® Anti-Friction Skirt Coating: reduces drag, scuffing, friction, cylinder bore wear, and reduces piston noise.
Hard Anodized Top Ring Grooves (PowerPak+ Piston Kits): extra protection against ring groove microwelding for extreme duty applications.
4032 or 2618 Aluminum Alloy: whether building a high performance street engine or an all out race engine, both 4032 and 2618 alloys are available depending on the application.
