JE Pistons forged 8-cylinder piston kit for LS applications with a 4.130 in bore and 32.40 cc dome. JE applies decades of racing development to produce pistons engineered, forged and machined 100% in the USA that are built for durability and consistent power in demanding engines. The FSR forging reduces skirt width and friction; accumulator groove and skirt coating are employed depending on application to improve ring seal and reduce wear. Forged from 2618 aluminum and tailored per engine.
