JE Pistons 5.4 4V MODULAR 11:1 Set of 8 Pistons

If you're rebuilding the top end of your 5.4 4V Modular engine for serious performance, a set of high-quality forged pistons is essential. These JE Pistons are built to handle the stress of high-demand applications, offering a robust foundation for your build. They feature an 11:1 compression ratio, designed to work with specific cylinder heads and camshafts to optimize power output for naturally aspirated or forced induction setups.

Crafted from 2618 aluminum right here in the USA, these pistons are forged for exceptional strength and durability. JE Pistons incorporates their proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear, contributing to a longer lifespan and more efficient operation. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, ensuring consistent ring seal and preventing flutter. Some applications also feature a skirt coating to further minimize friction and noise, while improving cylinder wall wear.

This set includes all eight pistons, ready for installation. Remember that these pistons are not CARB approved and cannot be shipped to California. For optimal results and proper fitment, always consult your engine builder or the manufacturer's installation guide to ensure compatibility with your specific engine components and build goals.
