Ultra Series forged pistons from JE are the industry?s strongest, most fully featured pistons available off the shelf. Offered for a wide range of domestic applications from LS to Big Block and HEMI to Ford Modular, Ultra Series pistons feature JE?s proprietary Aligned Grain Flow forging technology providing next-level tensile strength ideal for the extreme cylinder pressures of power adder engine builds. Equipped with custom level features including thermal barrier crown coating, skirt coating, gas ports, and more, Ultra Series are the ideal pistons for your boost-heavy or nitrous-huffing V8 engine build. As with all JE Pistons products, Ultra Series pistons are made 100% in the USA.
Aligned 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 environments
Thermal Barrier Crown Coating: This ceramic-based coating reflects heat into the combustion chamber, therefore reducing piston crown temperatures and improving exhaust gas scavenging
High-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 builds
Skirt Coating: Reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise, especially on cold start
Optimized Pin Oiling: Enhanced pin oiling features keep pin, pin bores, and small-end lubricated for reduced heat, friction, and wear
Lateral Gas Ports: Help maintain power-producing ring seal at the top compression ring, even in high RPM and high boost situations
These pistons utilize our dedicated Forged Side Relief (FSR) forging that was specifically designed to increase strength.
Designed for Power: Every feature on Ultra Series Pistons are optimized to perform high-horsepower racing engines
