Features and Benefits

  • Designed for Power: Every feature on Ultra Series Pistons are optimized to perform high-horsepower racing enginesAligned Grain Flow Technology: Exclusively available on JE Ultra Series, this proprietary, in-house forging process maximizes tensile strength to withstand the stresses of high-performance engine environmentsSkirt Coating: Reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise, especially on cold startThermal Barrier Crown Coating: This ceramic-based coating reflects heat into the combustion chamber, therefore reducing piston crown temperatures and improving exhaust gas scavengingHigh-Strength Wrist Pins: Premium thick-wall wrist pins are manufactured by Trend Performance in the USA and are designed for the demands of high-performance/power-adder buildsLateral Gas Ports: Help maintain power-producing ring seal at the top compression ring, even in high RPM and high boost situationsOptimized Pin Oiling: Enhanced pin oiling features keep pin, pin bores, and small-end lubricated for reduced heat, friction, and wearMade 100% in the USA
