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.

Quality equipment and more!!!
How can we order
I hope JE had improved.. ive had too many failures lately with JE pistond.
This is what passion and community is all about!! When a crazy storm rolled through the Englishtown, NJ round of Formula DRIFT, Jeff Jones quickly found that nobody in his pit was hurt thankfully, but his competition car was. Some may think it's all over for the weekend, but his crew and FD peers came together and worked nonstop to get it ready to Saturday competition. This is a great example of why we love being a part of the performance racing industry 🤝
