JE Pistons has built a leading reputation with custom pistons. It’s JE’s bread and butter, and top engine builders in the automotive and powersports industry rely on JE to make their design concepts reality. However, JE now offers shelf-stock pistons with new levels of strength and features normally reserved for the custom market, and they dubbed it the Ultra Series.

Developed through extensive experience designing pistons for countless types of engines and racing disciplines, the challenge first came in finding out specifically how to address needs across a broad group of automotive applications, and now that technology has been molded to serve powersports engines producing even the highest horsepower numbers.

"We grabbed the best applications and looked at the features that everyone normally wanted as a full race product. We built those into something that people could get off the shelf.”
The trend in the industry is that racers, builders, and enthusiasts are on a time crunch and need parts yesterday, which includes high-end premium pistons. That’s the idea behind the Ultra Series. It was natural that JE adapt Ultra Series technology to the powersports market after achieving sweeping success in the automotive category, beginning with applications for the Ninja ZX-14 and Suzuki Hayabusa:

2006-2019 Kawasaki Ninja ZX-14
1999-2019 Suzuki GSX1300 Hayabusa
Both of these applications are offered in a variety of bore size and compression ratio combinations.
