JE Pistons Ultra Series Modular Ford Coyote Gen 1/2 3.65in Bore/3.65in Stroke Set of 8 Pistons

When you're building a serious Ford Coyote engine, especially one that's going to see boost or nitrous, you need pistons that can handle the pressure. This set of eight Ultra Series pistons from JE Pistons is built for exactly that. You get the pistons themselves, designed to handle extreme cylinder pressures, along with high-strength wrist pins from Trend Performance, which are crucial for keeping everything lubricated and reducing wear in high-performance applications. The set also includes lateral gas ports to help maintain a solid ring seal even at high RPMs and under heavy boost, ensuring you get consistent power delivery.

What sets these Ultra Series pistons apart is JE's proprietary Aligned Grain Flow forging technology. This process maximizes the tensile strength of the aluminum, making these pistons incredibly strong for demanding engine builds. They also come with some custom-level features you don't often see on off-the-shelf parts. The thermal barrier crown coating reflects heat back into the combustion chamber, which helps reduce piston crown temperatures and can improve how efficiently exhaust gases are scavenged. Plus, the skirt coating not only reduces friction and wear on the piston skirts and cylinder walls but also helps quiet down the engine, especially when it's cold.

These pistons are made 100% in the USA, with the wrist pins also coming from a US-based manufacturer. They're specifically designed for power-adder V8 engines, meaning every feature is optimized for high-horsepower racing applications. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that's ready for serious power, this set offers a well-built solution with advanced features.
