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
Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
These pistons utilize our dedicated Forged Side Relief (FSR) forging that was specifically designed to increase strength.
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
