Description

JE Pistons Big Chief GP 12/14-degree 632 Flat Top Series pistons are forged using 2618 aluminum, yielding high-tensile strength needed for high-demand performance applications, and they are designed specifically for each engine and use application to provide optimized performance durability. Big Chief 12/14-degree 632 flat tops feature JE Pistons' proprietary Forged Side Relief (FSR) design to minimize friction and power loss via reduced skirt width and saves additional weight with a shorter wrist pin. These single replacement pistons include a case hardened 5115 low carbon steel wrist pin.
