JE History
The origins of what we know today as JE Pistons can be traced back to 1912 and the Los Angeles foundry of William Jahns Sr. and his company W.H. Jahns. Employing the tagline, “Nothing but Pistons,” the W.H. Jahns company produced pistons and semi-finished pistons until 1948, when Jahns Sr. retired. Meanwhile, Jahns’ son, William “Uncle Bill” Jahns Jr., started and had been working on his company Jahns’ Racing Pistons since 1947. Shortly after, the business became Jahns’ Engineering Pistons, and was finally shortened to JE Pistons.
Through the following years, JE Pistons’ technology evolved, from mastering casting technology in the 60s to researching and implementing forging technology in the 70s. Numerical Controlled (NC) machines were introduced to manufacturing in the early 80s, which was quickly improved to the use of Computer Numerical Controlled (CNC) machines and a proprietary piston design and machining program in the mid-80s.

#FunFactFriday Thermal Barrier Crown Coating applied to the top of the piston is designed to reflect heat into the combustion chamber, thereby increasing exhaust gas velocity and greatly improving scavenging potential. The .0015” thick coating can also assist in extending piston life by decreasing the rate of thermal transfer. Thermal Barrier Crown Coating is a standard feature on all of our #je #UltraSeries pistons!

The final round of SuperMotocross at the Coliseum was iconic 🎇 Kenny was on rails at the #SMX rounds on his #jepistons powered RM-Z, but we also have to give it up to Jettson for going home with the big pay day 💸

I'm going to be honest trying to look and find something on these websites is a real pain in the ass. I miss the catalogs for at least able to go on the website and use it as a catalog but I haven't found the first piston on this site and I like your products but I sure don't like the way it's done
3,000 with h beams?! 😂 The explosion will get his views
3k hp on a steel h-beam?
