JE Forged Racing Pistons

JE Pistons can make it happen, and that's probably why more engine builders choose them. JE's success, though due to many factors, is mainly thanks to their high-tech, CNC-based manufacturing facility which produces thousands of accurate, identical pistons. JE was the first and is the only manufacturer to use Ultra-Crown 3-D technology. Considered an industry standard among the racing elite, this technology allows you to take advantage of one of racing's most guarded secrets. Note: Pistons sets are sold 8 per package except for Buick V6. Ford 302 Inverted Dome: These pistons are designed to be compatible with forced induction and nitrous applications. The valve reliefs are machined to accommodate larger valves and long duration, tight lobe separation cams.
