JE Pistons 4.6 4V MODULAR 11:1 Set of 8 Pistons

If you're building a high-performance 4.6L 4V modular engine, these JE Pistons are a solid choice. This set includes eight pistons designed with an 11:1 compression ratio, aiming for that sweet spot between power and reliability for many performance builds. JE Pistons has been making forged pistons for a long time, and they build these right here in the USA using 2618 aluminum, which is known for its strength needed in demanding applications.

What sets these apart is JE's experience in racing. They use a proprietary Forged Side Relief (FSR) design that helps reduce friction and weight by using a shorter wrist pin and narrower skirt. Depending on the specific application, you might also find an accumulator groove, which helps manage combustion gas pressure for better ring seal and consistent power. Some applications also feature a skirt coating to further cut down on friction and noise, while also reducing wear on the piston skirts and cylinder walls. These aren't just generic pistons; they're made specifically for the 4.6L 4V modular engine to give you optimized performance and durability.

This set is for the engine builder who wants a well-built, USA-made piston for a serious performance build. Keep in mind that these are not CARB approved and cannot be shipped to California. You'll want to check the full manufacturer specifications for details on bore size, dome volume, and pin dimensions to ensure they match your specific build requirements.
