• Patented Dual Velocity Gas Ports combine the benefits of traditional gas ports, reducing ring flutter and movement while optimizing fuel efficiency and power output?without the risk of carbon build-up
• 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
• 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
• Made 100% in the USA
