Icon Pistons Forged Piston Set for Pontiac with Rod Length

Icon Pistons forged piston sets for Pontiac V8 engines are built for high-performance and racing engine builds. They are also sold as Pontiac performance pistons or forged engine piston sets. Each piston is forged from 2618 aluminum alloy for strength and durability under demanding conditions.

Key Features:

• Forged 2618 alloy: This is a high-ductility alloy with about 1% silicon. It is heat treated for very high compression ratios, boosted applications and nitrous use.
• CNC-machined construction: The crown and valve reliefs are CNC machined. The skirts are machined on in-house CNC equipment.
• Top land mini groove technology and an accumulator groove help limit ring flutter and improve ring seal.
• Reinforced design: The skirt and pin boss struts are designed to handle the heavy loads from high cylinder pressures.
• Centered wrist pin: The pin uses a big-block Chevy pin diameter.
• Hardware: Wrist pins and spiral lock rings are included. Piston rings are sold separately.

These pistons suit stroker and performance Pontiac engine builds. Choose the variant that matches your engine's bore size and rod length.
