JE PISTONS: LT4 4.065" 1.320" ASYMET Dish -6.3cc(SET) - 353908

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 *Made 100% in the USA
