JE Pistons 5.4 3V MODULAR 11:1 Set of 8 Pistons

If you're rebuilding the engine in your 5.4L 3V Modular, choosing the right pistons is crucial for getting the performance and durability you need. This set of eight forged pistons from JE Pistons is built to handle the demands of a high-performance application, offering an 11:1 compression ratio for a noticeable bump in power over stock.

JE Pistons has been making forged pistons for a long time, and they build these right here in the USA using 2618 aluminum. This material is known for its strength, which is exactly what you want when you're pushing an engine hard. They've also incorporated features like a proprietary Forged Side Relief (FSR) design, which 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 to help keep combustion gases in check and improve ring seal, along with a skirt coating to cut down on friction and noise. These pistons are made specifically for the 5.4L 3V engine, ensuring they're optimized for both performance and longevity.

This kit includes everything you need for an 8-cylinder engine, with a bore size of 3.701 inches and a compression height of 1.320 inches. Keep in mind that these pistons are not approved for sale in California due to emissions regulations.
