What material are these JE Pistons made from?

These pistons are forged in the USA from 2618 aluminum. This material is chosen for its high tensile strength, which is necessary for high-demand performance applications.

What is the purpose 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 400 SBC engines?

This set is designed for 400 SBC engines and includes specific dimensions like a 4.130-inch bore and 0.927-inch pin. It's always best to confirm these specifications match your engine's requirements and build plan.

Product Details

JE Pistons is known for making well-built forged racing pistons, drawing on over 75 years of experience. They've applied that knowledge to this set of pistons for 400 SBC engines. These aren't just generic pistons; they're forged and machined 100% in the USA from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines under heavy demand. This set is designed specifically for the 400 SBC engine and its intended use, aiming for a balance of durability and performance.

You'll find some notable features here that contribute to improved engine function. The proprietary Forged Side Relief (FSR) 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, these pistons may also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also benefit from a skirt coating that reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This set includes eight pistons, each with a 4.130-inch bore, a 1.250-inch compression distance, and a 0.927-inch pin. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance 400 SBC engine, these pistons are made to handle the stress and deliver reliable power.
