What material are these pistons made from and why is it important?

These pistons are forged from 2618 aluminum. This alloy is chosen for its high tensile strength, which is essential for handling the high pressures and temperatures found in performance engines.

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

The FSR design uses a reduced skirt width and a shorter wrist pin. This construction helps to minimize friction and power loss while also saving weight, contributing to better overall engine performance.

Are there any special coatings or grooves on these pistons?

Depending on the specific application, these pistons may feature an accumulator groove to help reduce combustion gas pressure, improving ring seal. Some also include a skirt coating to reduce friction and wear on the cylinder walls, which can also help quiet engine operation.

Product Details

JE Pistons is known for making strong, reliable forged racing pistons, drawing on over 75 years of experience. This set of eight flat-top pistons is built for the popular 350 Small Block Chevy (SBC) engine, offering a solid foundation for a high-performance build. They are engineered and machined entirely in the USA, ensuring you get a well-built part designed for demanding applications.

These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see a lot of stress. JE Pistons uses a proprietary Forged Side Relief (FSR) design. This means the skirt is narrower and shorter, which not only saves weight but also helps reduce friction and power loss. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion pressure, leading to better ring seal and consistent power delivery. Some applications also include a skirt coating that further reduces friction and wear on the cylinder walls, contributing to a quieter engine operation and longer life.

This set is designed for a 4.040-inch bore with a flat-top design and a -2.0cc dish. The pin size is 0.927 inches, and the compression distance is 1.250 inches. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed specifically for each engine and use application to provide optimized performance and durability.
