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

JE Pistons is well-known for making strong, reliable internal engine components, and their Ultra Series pistons are a prime example of that commitment. If you're building a Ford Coyote Gen 1 or Gen 2 engine and pushing the limits with boost or nitrous, these pistons are designed to handle the extreme cylinder pressures you'll encounter. They offer a significant step up from stock components for serious performance builds.

What sets these Ultra Series pistons apart is JE's proprietary Aligned Grain Flow forging technology. This process maximizes the material's tensile strength, making them incredibly robust for high-performance engine environments. You'll also find custom-level features like a thermal barrier crown coating, which helps reflect heat back into the combustion chamber, reducing piston crown temperatures and improving how efficiently the engine scavenges exhaust gases. The included high-strength wrist pins, made by Trend Performance, are built to withstand the demands of power-adder builds. 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 during cold starts. Lateral gas ports are integrated to help maintain a solid ring seal even at high RPMs and under heavy boost, ensuring consistent power delivery.

This set includes everything you need for an 8-cylinder engine, with a 3.650-inch bore and a 3.650-inch stroke. Every feature on these pistons is optimized for high-horsepower racing engines, and they are proudly made 100% in the USA. Please note that these pistons are not CARB approved and cannot be shipped to California.
