JE Pistons 4.6 2V MODULAR 9.5:1 Set of 8 Pistons

If you're building a performance 4.6L 2V Modular engine, these JE Pistons are a solid choice for your rebuild. This set includes eight pistons designed to provide a 9.5:1 compression ratio, which is a popular target for many naturally aspirated or boosted builds looking for a good balance of power and pump gas compatibility. JE Pistons has been making forged pistons for a long time, and they build these right here in the USA using 2618 aluminum, a material known for its strength under high stress.

What sets these pistons apart is their construction. They feature JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear while also saving weight. Some applications, like this one, may also include an accumulator groove to help manage combustion pressure and keep your rings sealed tight, ensuring consistent power delivery. They might also come with a skirt coating to further cut down on friction and noise, making your engine run a little smoother and last longer. These are made specifically for the 4.6L 2V Modular engine, so they're built to handle the demands of performance use.

This set is for the pistons only. You'll need to source your own rings and wrist pins, though the specs listed indicate a 0.866-inch pin diameter. Remember, these are not CARB approved and cannot be shipped to California. If you're aiming for a robust and reliable engine build, these JE Pistons are a well-made component to start with.
