Description

The JE Pistons 312055 is an FSR Asymmetrical Dish/Inverted Dome piston kit for Chevrolet LS Gen III/IV engines, specifically the LS2 418. These high-performance forged pistons are crafted in the USA from 2618 aluminum alloy, designed for durability and optimized performance in high-demand applications. Key features include a proprietary Forged Side Relief (FSR) design to minimize friction and power loss, a shorter wrist pin for weight savings, accumulator grooves, and double pin oilers. The pistons are machined to accept 1.2mm, 1.5mm, and 3.0mm rings (rings sold separately).
