What material are these pistons made from?

These pistons are forged from 2618 aluminum. This material is selected for its high tensile strength, making it well-suited 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 a reduced skirt width and a shorter wrist pin, which also contributes to weight savings.

Are these pistons compatible with nitrous oxide (NOS)?

Yes, the 'W/NOS' in the product name indicates these pistons are designed for applications that utilize nitrous oxide. The materials and design are intended to withstand the increased demands of such setups.

Product Details

JE Pistons is offering a set of eight BIG CHIEF W/NOS pistons specifically for Big Block Chevrolet engines. These pistons are forged in the USA using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines pushed to their limits in high-demand performance applications. They are designed to be a direct fit for your specific engine and intended use, aiming for an optimal balance of durability and performance.

This set features JE Pistons' proprietary Forged Side Relief (FSR) forging design. This design helps minimize friction and power loss by using a reduced skirt width, and it also saves weight with a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, which can reduce ring flutter and improve ring seal for more consistent power delivery. Additionally, some applications receive a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life.

This piston set is intended for high-performance builds, including those utilizing nitrous oxide (NOS). It's important to note that these pistons are not CARB approved and cannot be shipped to California. For installation, refer to the manufacturer's instructions for specific details regarding pin fitment and assembly.
