SUB FA20/TY 4UGS KIT

Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications. Designed specifically for each engine and use application to provide optimized performance durability. Proprietary Forged Side Relief (FSR) forging design minimizes friction and power loss with reduced skirt width and saves additional weight with a shorter wrist pin. Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise. Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power. Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings. Made 100% in the USA.
