Ultra Series combines all our premium features and a revolutionary new forging technology into an off-the-shelf piston kit! This includes an Aligned Grain Flow Forging, a proprietary JE technology that aligns forging grain flow in critical areas to improve strength.
• Designed for Power: Every feature on Ultra Series Pistons are optimized to perform flawlessly in high horsepower racing engines. This includes lateral gas ports, thicker ring lands, and dual pin oiling.
• Aligned Grain Flow Forging: Exclusively available on JE Ultra Series, these optimized 2618 alloy forgings offer added strength over traditional 2618 forgings.
• “Perfect Skirt” Coating: This patented skirt coating reduces friction and provides a tighter clearance that eliminates cold-start slap and false knock on computer-controlled engines.
• Thermal Barrier Crown Coating: This ceramic-based coating reflects heat into the combustion chamber, therefore reducing piston crown temperatures and improving exhaust gas scavenging.
• 9310 Alloy Wrist Pins: These high strength, premium thick wall wrist pins are manufactured by Trend Performance in the USA.
