What material are these JE Pistons made from?

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

What is the Forged Side Relief (FSR) design?

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

Are these pistons compatible with all 350 engines?

This set is specifically designed for 350 Small Block Chevy engines with a 4.035-inch bore. While they are intended for performance builds, it's always best to verify compatibility with your specific engine's requirements and build plan.

Product Details

If you're building a high-performance 350 Small Block Chevy, JE Pistons has you covered with this set of eight forged pistons. These aren't your average pistons; they're crafted with over 75 years of racing experience behind them, designed to handle the rigors of demanding engine builds. Engineered, forged, and machined entirely in the USA, they represent a serious commitment to durability and performance for your engine.

What sets these pistons apart is their construction using 2618 aluminum, a material chosen for its high tensile strength, which is crucial for high-demand applications. JE Pistons also incorporates their proprietary Forged Side Relief (FSR) forging design. This design helps minimize 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 to help reduce combustion gas pressure, leading to better ring seal and consistent power. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set is specifically designed for the 350 Small Block Chevy engine, with a 4.035-inch bore and a flat-top design. They are intended for performance builds where durability and optimized power output are key. Please note that these pistons are not CARB approved and cannot be shipped to California.
