JE Pistons Gen 3 Coyote 5.0 Ultra Series 3.661in Bore 11:1 CR 1.5cc Dome Pistons - Set of 8 Pistons

If you're building a high-horsepower Gen 3 Coyote 5.0L engine, these Ultra Series pistons from JE Pistons are a solid choice. They're designed to handle the extreme cylinder pressures that come with boosted or nitrous applications. This set includes eight pistons, each with a 3.661-inch bore and an 11:1 compression ratio, featuring a 1.5cc dome to help achieve that specific compression target.

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 exceptionally robust for demanding engine builds. They also come with custom-level features usually found only in fully bespoke builds. The thermal barrier crown coating reflects heat back into the combustion chamber, helping to keep piston crown temperatures down and improving how efficiently exhaust gases are scavenged. For reduced friction and wear on the skirts and cylinder walls, a skirt coating is applied, which also helps quiet down operation, especially during cold starts. Lateral gas ports are included to help maintain a strong ring seal even at high RPMs and under significant boost pressure.

These pistons are made 100% in the USA, including the high-strength, thick-wall wrist pins manufactured by Trend Performance. They are optimized for power, with every feature geared towards high-horsepower racing engines. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're aiming for serious power with your Coyote build, these pistons are built to take it.
