What material are these pistons made from?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is crucial for high-demand performance engine applications.

What is the benefit 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.

Are these pistons compatible with all Small Block Chevrolet engines?

These pistons are specifically designed for Small Block Chevrolet engines with a 4.045 inch bore. It's always recommended to verify compatibility with your specific engine build and any modifications you may have.

Product Details

If you're building a high-performance Small Block Chevrolet engine, these JE Pistons SBC FSR TOUR SERS GP pistons are a solid choice. JE Pistons has been making forged pistons for over 75 years, and they build these right here in the USA using 2618 aluminum. This material gives them the strong tensile strength needed for demanding performance applications, whether you're hitting the drag strip or the dirt track.

What sets these apart is JE's proprietary Forged Side Relief (FSR) design. This means they've worked to minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Some applications might also include an accumulator groove, which helps control combustion gas pressure to improve ring seal and keep power consistent. You might also find a skirt coating, which further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down engine noise.

This set is designed specifically for the Small Block Chevrolet engine with a 4.045 inch bore. They feature a flat top design and come with a 0.927 inch pin. Remember, these pistons are not CARB approved and cannot be shipped to California. They are sold as a set of 8.
