What material are these JE Pistons made from?

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

What is the Forged Side Relief (FSR) design?

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

Are these pistons compatible with all Big Block Chevrolet engines?

This is a set of pistons designed for Big Block Chevrolet (BBC) engines with a 4.350 inch bore. While they are intended for BBC applications, it's always best to verify specific engine compatibility and required clearances with your engine builder or manufacturer's specifications.

Product Details

This is a set of eight JE Pistons BBC pistons, designed for high-performance applications. You get the pistons themselves, ready to be installed in your Big Block Chevrolet engine. These pistons are forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that demand a lot of power and durability.

JE Pistons has been making performance pistons for over 75 years, and they've put that experience into this set. They feature a proprietary Forged Side Relief (FSR) design that helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also saves weight. Depending on your specific application, these pistons might also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power. Some applications also come with a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also quiet down engine noise.

These pistons are made specifically for your engine and intended use, aiming for the best balance of performance and longevity. They are forged and machined entirely in the USA. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
