Overview

JE Pistons 23º 350 & 400 F.S.R. HOLLOW DOME GP (GAS PORTED) pistons are designed for circle track and drag racing. They are up to 70 grams lighter than traditional full round pistons (including wrist pin and rings) while maintaining strength and durability through FEA-designed forging. Features include deeper valve pockets for higher lift cams, an accumulator groove, contact reduction grooves, double pin oilers, and lateral gas ports. They accept a low friction .043/.043/3.0mm ring package. Includes Pin #927-2250-15-51C (106g) and Wire Locks #927-073-MW. Made in the USA from forged 2618 aluminum for high tensile strength in performance applications. The proprietary Forged Side Relief (FSR) design minimizes friction and power loss with reduced skirt width and a shorter wrist pin for weight savings.
