What materials are these JE Pistons made from?

These JE 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 purpose of the Forged Side Relief (FSR) design?

The proprietary Forged Side Relief (FSR) design helps to minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight.

Are there any special coatings or grooves on these pistons?

Depending on the specific application, these pistons may feature an accumulator groove to help reduce combustion gas pressure and improve ring seal. They may also include a skirt coating to reduce friction and wear, as well as operating noise.

Product Details

This is a set of eight JE Pistons, specifically designed for a 427 Big Block Ford (BBF) engine with an inverted dome design. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for high-demand performance applications where durability is critical. Each piston features a 4.310-inch bore and an inverted dome with a volume of -25.0cc, designed to work with specific cylinder head configurations for optimized combustion. The set includes the pistons, wrist pins, and locks, ready for installation into your performance engine build.

JE Pistons brings over 75 years of experience to their forged piston designs, and this set is no exception. They are engineered and machined entirely in the USA, ensuring a high level of manufacturing control. The proprietary Forged Side Relief (FSR) forging design is incorporated to minimize friction and power loss by reducing skirt width and utilizing a shorter wrist pin, which also saves weight. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for consistent power delivery. A skirt coating, also application-dependent, is used to further reduce friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer component life.

When building a high-performance engine, the pistons are a critical component. JE Pistons are proven in various racing environments, from dirt tracks to drag strips, and are a popular choice for those seeking reliable performance. This set is designed specifically for the 427 BBF engine and its intended use, aiming for an optimal balance of performance and durability. Please note that this part is not CARB approved and cannot be shipped to California.
