JE Pistons 4.6L/5.4L Modular FSR Pistons 314614

JE Pistons 4.6L/5.4L modular FSR pistons utilize their dedicated 2618 alloy Forged Side Relief (FSR) forging that was specifically designed for high-horsepower modular engines. They have engineered these pistons with extra weight-saving and durability measures in place for both street and racing applications. Accumulator grooves provide additional volume when residual combustion gases that have "blown by" the top ring can collect. Additional volume reduces pressure between the top and middle rings, adding in top ring seal and reducing ring flutter. Lightweight and extremely durable, JE modular FSR pistons are machined for 1.0mm, 1.2mm, 2.8mm, and 1.2mm, 1.5mm, 3.0mm rings.
