What material are these JE Pistons made from?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for high-demand performance applications.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary JE Pistons feature that helps minimize friction and power loss. It achieves this through reduced skirt width and a shorter wrist pin, which also contributes to saving weight.

Are these pistons compatible with all 350 engines?

These pistons are designed for 350 Small Block Chevy engines and are specifically engineered for performance applications. It's important to confirm that the bore size (4.030 inches) and compression distance (1.550 inches) match your engine's requirements.

Product Details

If you're building a high-performance 350 Small Block Chevy engine, a solid set of pistons is where you start. These JE Pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demands of racing and performance applications. They are designed specifically for the 350 SBC engine, ensuring they work with your build.

JE Pistons brings over 75 years of experience to the table with these forged pistons, manufactured entirely in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width and using a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, improving ring seal and maintaining consistent power. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes eight flat-top pistons, each with a 4.030-inch bore, a 1.550-inch compression distance, and a 0.927-inch pin. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds and are a popular choice for those looking to maximize the potential of their 350 engine.
