Founded in 1947 by William "Bill" Jahns Jr. as Jahns' Racing Pistons and headquartered in Mentor, Ohio, JE Pistons forges, machines, and finishes every piston in-house at its US facility. The Pro Series 2618 line covers high-boost forced-induction and nitrous builds, while SRP and SRP Pro pistons serve naturalised street-strip applications, and the Ultra Series introduces Aligned Grain Flow forging with ceramic crown coatings for power-adder programmes. JE supplies engine builders across NHRA drag racing, NASCAR, IMSA sports-car endurance, and rally, with off-the-shelf and custom forgings for LS, Coyote, K-series, 2JZ, RB, EJ and European turbocharged four-cylinder platforms.
