JE Pistons CHRYSLER TOP FUEL Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This material choice provides the high tensile strength needed when you're pushing an engine hard, whether that's on the drag strip or in a serious street build. JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA to ensure they meet the rigorous demands of racing and high-performance engines.

Each piston in this set features JE's proprietary Forged Side Relief (FSR) design. This isn't just about looks; it's a functional choice that minimizes friction and power loss by reducing skirt width. The shorter wrist pin also contributes to saving weight. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure to reduce ring flutter and improve ring seal for more consistent power delivery. Some applications also include a skirt coating designed to cut down on friction and wear, while also making the engine run a bit quieter.

This set is designed specifically for Chrysler 8-cylinder engines with a 4.187-inch bore. It includes eight flat-top pistons, each with a 1.630-inch compression distance and a 1.156-inch pin diameter. These are a solid option if you're rebuilding or upgrading a performance-oriented Chrysler V8 and need pistons that can handle serious power.
