JE Pistons Ultra Series Modular Ford Coyote Gen 1/2 3.64in Bore/3.65in Stroke Set of 8 Pistons

Starting with JE Pistons' proprietary Aligned Grain Flow forging technology, these Ultra Series pistons are built to handle the intense cylinder pressures found in boosted or nitrous-fed Ford Coyote Gen 1 and Gen 2 engines. This advanced in-house process maximizes the material's tensile strength, making them exceptionally well-suited for high-horsepower racing applications where durability is paramount.

Beyond the core forging, these pistons come equipped with features typically found only in custom builds. A ceramic-based thermal barrier crown coating helps reflect heat back into the combustion chamber, reducing piston crown temperatures and improving exhaust gas scavenging. The skirts are treated with a friction-reducing coating that also quiets operation, especially during cold starts, and helps minimize wear on both the piston and cylinder walls. Lateral gas ports are incorporated to maintain a strong seal on the top compression ring, even at high RPMs and under significant boost. Each set includes high-strength, thick-wall wrist pins manufactured by Trend Performance, designed specifically for the rigors of power-adder builds. Enhanced pin oiling features ensure consistent lubrication, further reducing heat and wear in this critical area.

This set is designed for an 8-cylinder engine with a 3.640-inch bore and includes all eight pistons. Remember, these pistons are not CARB approved and cannot be shipped to California. For serious Coyote engine builds aiming for maximum performance and reliability, these JE Pistons offer a well-built, feature-rich solution made entirely in the USA.
