Description
Engineered and machined in the USA, this piston utilizes 2618 aluminum for high tensile strength and durability. It incorporates JE Pistons' proprietary Forged Side Relief (FSR) design, which minimizes friction and power loss through a reduced skirt width and a shorter wrist pin. The piston also includes an accumulator groove to improve ring seal and consistent power.
