JE Pistons 440 MOPAR DISH Set of 8 Pistons

When you're building a serious Mopar big block, you need pistons that can handle the stress and deliver consistent power. This set from JE Pistons gives you eight forged pistons specifically made for the 440 engine. They're crafted from 2618 aluminum, a material known for its high tensile strength, which is crucial for high-demand performance applications where reliability is key.

JE Pistons brings over 75 years of experience to the table, and these pistons are forged and machined entirely in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width. This design also saves weight, especially when paired with a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove, which helps reduce combustion gas pressure to prevent ring flutter and improve ring seal for steady power output. Some applications also include a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also lead to quieter operation.

This set is designed for a 4.375 inch bore with an inverted dome/dish shape. It's important to note that these pistons are not CARB approved and cannot be shipped to California. For a high-performance Mopar build, these pistons offer a well-built foundation for your engine.
