JE Pistons, a leader in high-performance forged and billet racing pistons, has redesigned and expanded its product offering for the Ford Modular 4.6L and 5.4L engines along with releasing new part numbers for the Ford Modular Coyote 5.0L. These new JE Pistons utilize a dedicated 2618 alloy Forged Side Relief (FSR) forging that was specifically designed for high horsepower modular engines.
Additionally, JE has engineered this piston with extra weight-saving and durability measures in place for both street and racing applications. The expansion includes a total of 150 off-the-shelf pistons for popular 2-valve, 3-valve and 4-valve configurations. 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. Premium gas nitrided rings provide maximum life for all applications and a brush dome eliminates sharp edges for a ready-to-install finish. Premium rings are standard for all three applications.
