The standard Mopar 440 Pack Pistons feature a forged aluminum construction, which provides superior strength and durability compared to cast pistons.

This, in turn, helps to reduce oil consumption and improve overall engine performance. The pistons also feature a single-compression ring design, which provides a balanced pressure distribution between the top and second rings, further improving ring seal and reducing oil consumption.
In addition to their performance benefits, the Mopar 440 Pack Pistons are also engineered for easy installation. They come with chamfered skirt edges, which provide a smooth transition between the skirt and the cylinder wall, making installation easier and reducing the risk of damage to the cylinder wall. The pistons also feature a precision-machined piston pin bore, which ensures a perfect fit for the piston pin and reduces the risk of pin bending or damage.
Overall, the Mopar 440 Pack Pistons (Part Number: 3420218) are a high-quality, performance-enhancing upgrade for any 1970 or 1971 Mopar muscle car.
