The Icon pistons are made from forged 4032 aluminum, known for its durability and resistance to expansion under high temperatures. They come with plasma-moly standard gap rings, which help with sealing and oil control. King XP rod and main bearings are included, offering robust protection for the crankshaft and connecting rod journals under heavy load.
This balanced assembly is designed to reduce vibration and ensure smooth operation at higher RPMs. It's important to note that this part is not CARB approved and cannot be shipped to California.
