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 engine applications.

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

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

Are these pistons compatible with all Coyote 5.0 engines?

This set is designed for the Coyote 5.0 Modular engine and features an 11:1 compression ratio. It's important to verify that this specific compression ratio and bore size are suitable for your engine build. These pistons are not CARB approved and cannot be shipped to California.

Product Details

If you're building a high-performance Coyote 5.0 engine, these JE Pistons are a solid choice. This set includes eight forged pistons designed specifically for the 5.0 Modular engine, featuring an 11:1 compression ratio. JE Pistons has been making performance pistons for over 75 years, and these are forged, engineered, and machined entirely in the USA.

These pistons are made from 2618 aluminum, which gives them the strong tensile strength needed for demanding performance applications. They feature JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design also saves weight by using a shorter wrist pin. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, improving ring seal and preventing flutter. Some applications also feature a skirt coating that reduces friction and noise while minimizing wear on the piston skirts and cylinder walls.

This is a set of eight pistons, each with a 3.650-inch bore and a dome volume of 2.7cc, contributing to the 11:1 compression ratio. They use a 0.866-inch wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California.
