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 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 Chrysler Small Block engines?

This set is designed for Chrysler Small Block engines with a 4.040 inch bore. While they are engineered for performance, it's always best to verify specific engine compatibility and ensure all necessary components like rings and pins are correctly sized and installed according to manufacturer instructions.

Product Details

JE Pistons is known for making well-built forged racing pistons, and they've put over 75 years of experience into this set for Chrysler Small Block engines. These aren't just off-the-shelf parts; they're engineered, forged, and machined entirely in the USA, specifically for demanding performance applications. Using 2618 aluminum, these pistons offer the high tensile strength needed when you're pushing your engine hard, whether that's on the track or for serious street performance.

This set features JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, saving weight in the process. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise. These pistons are designed for a 4.040 inch bore, with a 1.665 inch compression distance and a 0.927 inch pin diameter.

This set includes eight pistons, ready to be installed in your Small Block Chrysler engine. Please note that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance engine and need pistons that are proven in competition, this set from JE Pistons is a solid option.
