    Manufacturer's Part Number:

    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.

    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.

    Note: Pistons sets are sold 8 per package except for Buick V6.

    Can you get a JE. Piston pn# 170692 as a signal thank you Rich

    Asked by: Rich46
    Single pistons can be ordered. We will need to know if it is a left or right side piston before ordering.
