What material are these JE Pistons made from?

These pistons are forged in the USA using 2618 aluminum. This material is chosen for its high tensile strength, which is crucial for high-demand performance applications.

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

The 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 on the piston assembly.

Are these pistons legal for use in California?

No, these pistons are not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

JE Pistons has been a leader in forged racing pistons for over 75 years, and they've put that experience into this set of BBC pistons. These are built for high-demand performance applications, forged right here in the USA from 2618 aluminum, which gives them the strong tensile strength you need when you're pushing your engine hard. They're designed specifically for the BBC engine and its intended use, aiming for that sweet spot between durability and performance.

You'll find a few notable features here that set these pistons apart. The proprietary Forged Side Relief (FSR) forging design helps cut down on friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to prevent ring flutter and keep your rings sealing consistently for reliable power. Some applications also include a skirt coating designed to reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet things down a bit.

This is a set of 8 pistons, designed for a 4.600 inch bore. They are built to be a direct fit for BBC engines, and JE Pistons machines them 100% in the USA. Keep in mind that these are not CARB approved and cannot be shipped to California.
