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 engine applications.

Are these pistons compatible with all cylinder heads?

These pistons are specifically designed for 18-degree cylinder heads. Using them with a different cylinder head angle may affect performance and proper engine function.

What is the purpose of the Forged Side Relief (FSR) design?

The FSR design helps to minimize friction and power loss by reducing the width of the piston skirt. It also contributes to weight savings by allowing for a shorter wrist pin.

Product Details

If you're building a high-performance 400 Small Block Chevy engine, a solid set of pistons is crucial for durability and power. This set from JE Pistons is forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for the demands of performance applications. These pistons are designed specifically for the 400 SBC engine, ensuring they work correctly with your specific build.

JE Pistons has been a leader in forged racing pistons for over 75 years, and they machine these 100% in the USA. They feature a proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help reduce combustion gas pressure, improving ring flutter and seal for consistent power. A skirt coating, also application-dependent, can further reduce friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This set includes eight pistons, each with a 4.130-inch bore and a dome volume of 2.50 cc, designed for an 18-degree cylinder head configuration. The included wrist pins measure 0.927 inches in diameter. Please note that these pistons are not CARB approved and cannot be shipped to California.
