JE Pistons FSR Piston Set (EJ25)
The pistons are made from a 2618 T6 high tensile forged aluminum. JE piston designs are specifically engineered for extreme applications up to, and including, professional competition. In this environment, the higher compression ratios, highest boost or heavy nitrous usage necessitate the higher tensile strength 2618 aluminum alloy. The design includes dome and dishes feature smooth flowing radii for excellent flame travel.
