JE Pistons 4.040 350 SBC FT Set of 8 Pistons

If you're building a high-performance 350 Small Block Chevy, these JE Pistons are a solid choice. They're designed for a 4.040 inch bore and feature a flat-top design, ready to be paired with your chosen cylinder heads and camshaft for a custom build. JE Pistons has been making forged pistons for over 75 years, and these are made entirely in the USA from 2618 aluminum, which gives them the high tensile strength needed for demanding applications.

What sets these pistons apart is their proprietary Forged Side Relief (FSR) design. This means they have a reduced skirt width, which helps minimize friction and power loss, while also saving weight. Depending on the specific application, you might also find an accumulator groove, which helps reduce combustion gas pressure to prevent ring flutter and improve ring seal for consistent power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise. JE Pistons engineers each set specifically for the intended engine and use, ensuring you get optimized performance and durability.

This set includes eight pistons, all forged and machined in the USA. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. They are designed for serious performance builds where durability and power are key.
