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

This is a set of eight JE Pistons Ultra Series pistons, designed specifically for Ford Coyote Gen 1 and Gen 2 engines with a 3.64-inch bore and a 3.65-inch stroke. These aren't your average pistons; they're built to handle serious power, especially if you're adding boost or nitrous. They come with high-strength wrist pins from Trend Performance, which are crucial for keeping things lubricated and reducing wear under extreme conditions.

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 tough and able to withstand the high cylinder pressures found in boosted V8s. You also get a thermal barrier crown coating, which is a ceramic-based layer that reflects heat back into the combustion chamber. This helps keep piston crown temperatures down and can improve how efficiently exhaust gases are scavenged. Plus, the skirt coating helps reduce friction and noise, especially when the engine is cold.

JE also included lateral gas ports, which are designed to help maintain a solid seal on the top compression ring, even at high RPMs and under heavy boost. These pistons are optimized for high-horsepower racing engines and are made entirely in the USA. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a high-performance build, you'll want to consult the manufacturer's installation instructions for specific details on ring gap, bearing clearance, and assembly.
