As the leader in forged racing pistons, JE Pistons has applied over 75 years of experience to its range of Ultra Series pistons - The Strongest Pistons in Powersports. The Ultra Series combines all their 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.
JE Pistons is the leader in forged racing pistons. With 70-plus years of experience, in-house forging, and industry-leading technology, JE Pistons are designed to perform at the top levels of all forms of motorsports.
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
"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
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
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
These pistons utilize our dedicated Forged Side Relief (FSR) forging that was specifically designed to increase strength.
Aligned Grain Flow Forging - These optimized 2618 alloy forgings offer added strength over traditional 2618 forgings.
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
