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 will see boost or nitrous, you need pistons that can handle the extreme cylinder pressures. These Ultra Series pistons from JE Pistons are built for just that. They're designed to be the strongest, most feature-rich pistons you can get right off the shelf, ready for serious power adder applications.

What sets these apart is JE's proprietary Aligned Grain Flow forging technology. This process maximizes the metal's tensile strength, giving these pistons the backbone 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 piston crown temperatures down and can even improve how efficiently exhaust gases are scavenged. The skirts are coated too, which cuts down on friction and wear against the cylinder walls, leading to a quieter engine, especially when it's cold.

Beyond the coatings, these pistons include lateral gas ports. These are strategically placed to help maintain a solid seal on the top compression ring, even when you're dealing with high RPMs and significant boost. They also come with premium, thick-wall wrist pins from Trend Performance, built to handle the rigors of high-performance builds. Every feature on these Ultra Series pistons is optimized for high-horsepower racing engines, and they're all made 100% in the USA.
