JE Pistons 13
JE recently added to its lineup of circle track pistons with an all-new, 13-degree, small block Chevy design. JE worked closely with engine builders to design a dome and valve pocket profile that fits almost all aftermarket 13-degree SBC cylinder heads on the market.
Features include vertical gas ports, contact reduction grooves, a power-added accumulate groove, double pin oiling with broaches, and more.
