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.

• "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.
• 9310 Alloy Wrist Pins: These high strength, premium thick wall
• Accumulator groove (depending on application) helps reduce pressure from combustion gases, reducing ring fluttering and improving ring seal for consistent power
• Aligned Grain Flow Forging - These optimized 2618 alloy forgings offer added strength over traditional 2618 forgings.
• Designed specifically for each engine and use application to provide optimized performance durability
• Engineered, forged and machined 100 percent in the USA
• 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
• Forged in the USA using 2618 aluminum, yielding high tensile strength needed for high-demand performance applications
• Includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings
• Made 100% in the USA
• 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
• 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
• Skirt coating (depending on application) reduces friction and wear on piston skirts and cylinder walls while simultaneously reducing operating noise
• Thermal Barrier Crown Coating - This ceramic-based coating reflects heat into the combustion chamber, therefore reducing piston crown temperatures and improving exhaust gas scavenging
