Description

The JE Pistons 311967L is a single LS Gen III/IV flat top piston designed for extreme applications and professional competition. Constructed from forged 2618 aluminum, it offers high tensile strength to handle increased compression ratios and boost. The piston features a proprietary Forged Side Relief (FSR) design to minimize friction and power loss, with reduced skirt width and a shorter wrist pin for weight savings. This piston is sold individually and fits the left side exhaust valve orientation.
