Product Details

If you're building or rebuilding a 350 Small Block Chevy engine, these JE Pistons are a solid choice for performance and durability. JE Pistons has been making forged pistons for a long time, and they build these right here in the USA using 2618 aluminum. This material gives them the strong tensile strength needed for high-demand applications, whether you're hitting the drag strip or just want a well-built engine for your street machine.

What sets these apart is their specific design for the 350 SBC. They feature a proprietary Forged Side Relief (FSR) forging design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight too. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, which improves ring seal for consistent power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, helping to quiet things down and extend the life of your engine components.

This set includes eight flat-top pistons designed for a 4.040-inch bore. They are made 100% in the USA, ensuring you're getting a well-made part built for performance. Keep in mind these are not CARB approved and cannot be shipped to California. You'll want to refer to the manufacturer's instructions for specific installation details, including ring and pin selection, as these are typically sold separately.
