- Designed for Power: Every feature on Ultra Series Pistons are optimized to perform high-horsepower racing engines
- 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
- Skirt Coating: Reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise, especially on cold start
- 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
- Lateral Gas Ports: Help maintain power-producing ring seal at the top compression ring, even in high RPM and high boost situations
- Optimized Pin Oiling: Enhanced pin oiling features keep pin, pin bores, and small-end lubricated for reduced heat, friction, and wear
- Made 100% in the USA
