What material are these JE Pistons made from?

These pistons are forged in the USA 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 FSR forging design helps to minimize friction and power loss by reducing the piston skirt width. It also contributes to weight savings, especially when used with a shorter wrist pin.

Are these pistons compatible with all 426 HEMI engines?

This set is designed specifically for the 426 HEMI engine and includes a 4.280-inch bore. It's always recommended to confirm the specific bore size and piston type match your engine's requirements for optimal performance.

Product Details

When you're rebuilding the heart of a legendary 426 HEMI, you need components that can handle the power and endure the stress of high-performance driving. This set of eight forged pistons from JE Pistons is built specifically for that purpose, offering a robust solution for serious engine builds.

Crafted in the USA from 2618 aluminum, these pistons are well-built to provide the high tensile strength required for demanding applications. JE Pistons incorporates their proprietary Forged Side Relief (FSR) forging design, which helps minimize friction and power loss by reducing skirt width. This design also contributes to weight savings, especially when paired with a shorter wrist pin. 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, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

JE Pistons has over 75 years of experience in forging racing pistons, and this expertise is evident in every set. Each piston is designed specifically for the 426 HEMI engine and its intended use, ensuring optimized performance and durability. This set includes everything needed to outfit an 8-cylinder engine, with a 4.280-inch bore and a dome piston design.
