JE Pistons Ultra Series Modular Ford Coyote Gen 1/2 3.63in Bore/3.65in Stroke Set of 8 Pistons

If you're building a high-horsepower Ford Coyote engine, especially one that's going to see boost or nitrous, you need pistons that can handle the extreme cylinder pressures. These Ultra Series pistons from JE Pistons are designed specifically for that kind of demanding application. They're not just off-the-shelf parts; they come with custom-level features built right in to help your engine make serious power and last.

What sets these apart is JE's proprietary Aligned Grain Flow forging process. This in-house technology maximizes the material's tensile strength, giving these pistons the solid foundation needed for boosted or nitrous-fed V8s. You also get a thermal barrier crown coating, which is a ceramic-based material that reflects heat back into the combustion chamber. This helps keep the piston crown cooler and can improve how efficiently exhaust gases are scavenged. For reduced friction and wear on the cylinder walls and piston skirts, there's a specialized skirt coating, which also helps quiet things down, especially during a cold start. Plus, lateral gas ports are included to help maintain a strong seal on the top compression ring, even at high RPMs and under heavy boost.

These pistons are made from 2618 aluminum and feature an inverted dome/dish design with a 3.630-inch bore. They come with high-strength, thick-wall wrist pins manufactured by Trend Performance. Every feature on these Ultra Series pistons is optimized for high-horsepower racing engines, and they're made 100% in the USA. Keep in mind these are not CARB approved and cannot be shipped to California.
