JE Pistons forged 8-cylinder piston kit for LS applications with a 4.065 in bore and 29.20 cc dome. Manufactured by JE and finished in the USA, these forged pistons bring race-proven durability and consistent combustion control for high-output engines. The FSR forging lowers skirt width to reduce friction; accumulator groove and skirt coating may be used depending on application to improve ring seal and reduce wear.
