JE Pistons GM LS3 LS4 Stroker SRP Pro 2618 Pistons - Set of 8

These JE Pistons Stroker SRP Pro 2618 Pistons are a set of 8 designed to fit GM LS3 / LS4 engines. They are forged in the USA using 2618 aluminum, which provides high tensile strength for demanding performance applications. The pistons feature a proprietary Forged Side Relief (FSR) forging design that minimizes friction and power loss with reduced skirt width and saves weight with a shorter wrist pin. The ring groove design is engineered to maintain a positive seal in high-HP, boosted applications, and they have a stout top land thickness for improved strength. A low-friction skirt coating reduces wear, operating noise, and optimizes performance. The set includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings. An accumulator groove helps reduce pressure from combustion gases, preventing ring fluttering and improving ring seal for consistent power. These pistons are made 100% in the USA and are NOT CARB LEGAL.
