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

The FSR design is a JE Pistons innovation that minimizes friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight.

What materials are these pistons made from, and why is that important?

These pistons are forged from 2618 aluminum. This material provides the high tensile strength needed to withstand the demanding conditions of high-performance engine builds.

Are any special coatings or grooves included with these pistons?

Depending on the specific application, these pistons may include an accumulator groove to help reduce combustion gas pressure and improve ring seal. A skirt coating may also be present to reduce friction and wear, while also quieting operation.

Product Details

Forged from 2618 aluminum, these JE Pistons LS FT STROKER pistons are built for high-demand performance applications where strength and durability are critical. JE Pistons brings over 75 years of experience to their forged pistons, with this set specifically designed for LS engines. They are engineered, forged, and machined entirely in the USA, ensuring a well-built component ready for serious work.

The proprietary Forged Side Relief (FSR) design is a key feature, reducing friction and power loss by using a narrower skirt 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 delivery. A skirt coating, if included for your application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life. The flat-top design with a 4.125-inch bore and a -2.00 cc dish is ready for stroker builds.

This set includes eight pistons, each designed specifically for the LS engine to optimize performance and durability. While these pistons are made for high-performance use, please note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
