What material are these JE Pistons made from?

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

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

The FSR forging design helps to minimize friction and power loss by reducing the piston skirt width. It also contributes to weight savings by utilizing a shorter wrist pin.

Are these pistons compatible with all BBC engines?

These pistons are designed specifically for BBC engines and performance applications. It is recommended to verify the bore size and compression distance against your engine's specifications to ensure proper fitment.

Product Details

These JE Pistons BBC FT HD/BLOWN pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, making them well-suited for high-demand performance applications. Each piston in this set of eight is designed specifically for the BBC engine and its intended use, whether that's on the dirt track or the drag strip, aiming for an optimal balance of durability and performance. They are manufactured 100% in the USA, reflecting JE Pistons' extensive experience in creating forged racing pistons.

The design incorporates a proprietary Forged Side Relief (FSR) forging, which reduces skirt width to minimize friction and power loss, while also saving weight with a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for more consistent power delivery. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation.

This set includes pistons with a 4.530-inch bore, a 1.520-inch compression distance, and a 0.990-inch wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California. They are designed for performance builds where strength and reliability are paramount.
