ICON Elite Forged Pistons
If you are looking to step your engine program up to the next level, ICON Elite Series of pistons have exactly what you are looking for. Made exclusively from 2618 aluminum, the Elite Series is purpose built from top to bottom to perform consistently in extreme conditions.
ICON's Elite forged pistons feature their Line2Line adaptive skirt technology coating that reduces friction between the piston and cylinder wall, while providing additional protection at start-up. They come standard with an anodized top ring groove to greatly reduce micro-welding that can occur under detonation conditions, and an anodized piston crown to help focus the heat in the piston crown and improve combustion efficiency. Select Elite pistons designed for your build.
Additional features:
* Upgraded wrist pin
* Mini grooves
* CNC-machined valve reliefs and crown
* Diamond CNC-turned skirts
* Accumulator groove
* Dual forced pin oiling
* Lateral gas ports on high-compression designs
* Spacer rings provided for shorter compression height pistons
