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 necessary for high-demand performance applications.

What is the Forged Side Relief (FSR) design?

The FSR design minimizes friction and power loss by using a reduced skirt width. It also saves additional weight with a shorter wrist pin, contributing to overall engine efficiency.

Are these pistons compatible with all BBC engines?

This set is specifically designed for BBC engines in heavy-duty or blown applications. It's always best to verify compatibility with your specific engine build and requirements before purchasing.

Product Details

JE Pistons is known for its forged racing pistons, with over 75 years of experience building them for all sorts of demanding applications. This set of BBC FT HD/BLOWN pistons, part number 257978, is a prime example of their commitment to durability and performance. They are forged and machined entirely in the USA, using 2618 aluminum, which gives them the high tensile strength needed for engines that are pushed hard.

These pistons feature JE's proprietary Forged Side Relief (FSR) design. This means they have reduced skirt width and a shorter wrist pin, which helps minimize friction and power loss while also saving weight. Depending on the specific engine application, they may also include an accumulator groove to help manage combustion gas pressure, reducing ring flutter and improving ring seal for more consistent power. Some applications also get a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise.

This kit is designed specifically for the BBC engine and for heavy-duty or blown applications, meaning they are built to handle the extra stress. The set includes 8 pistons, each with a 4.560-inch bore and a flat top design with a -3.0cc dish. They use a 0.990-inch wrist pin and have a 1.520-inch compression distance. Please note that these pistons are not CARB approved and cannot be shipped to California.
