What material are these JE Pistons made from?

These pistons are forged from 2618 aluminum. This alloy is chosen for its high tensile strength, making it well-suited for high-performance and demanding engine applications.

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

The FSR design minimizes friction and power loss by using a reduced skirt width. It also saves additional weight with a shorter wrist pin, contributing to overall engine efficiency and performance.

Are these pistons compatible with all 400 small-block Chevy engines?

This set is specifically designed for 400 small-block Chevy V8 engines with a 4.125-inch bore. It's important to verify that your engine build matches the specifications like bore size and compression distance for optimal fitment.

Product Details

If you're building a high-performance 400 small-block Chevy engine, a solid set of pistons is crucial. This set from JE Pistons is designed specifically for that application, offering a robust foundation for serious power. They're forged in the USA from 2618 aluminum, a material known for its high tensile strength, which is exactly what you need when you're pushing an engine hard.

JE Pistons has been in the game for over 75 years, and they've put that experience into these pistons. They feature a proprietary Forged Side Relief (FSR) design, which means the piston skirts are narrower and shorter. This not only saves weight but also helps reduce friction and power loss. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to keep the rings seated properly and maintain consistent power. Some applications also include a skirt coating to further reduce friction and noise, while also cutting down on wear.

This set is for an 8-cylinder engine and features an inverted dome design with a 4.125-inch bore. The kit includes everything you need to outfit your 400 SBC, with a 0.927-inch pin diameter and a compression distance of 1.145 inches. Keep in mind these are not CARB approved and cannot be shipped to California.
