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.

Cory Probst putting our lightweight 2BBL pistons to work this week! These pistons are specifically designed for 2-barrel stock car racing, featuring window mills on the strut to reduce windage and remove weight, allowing cars to accelerate hard off the corners and charge down the straights. Available in bore sizes from 4.030in to 4.065in with .005in increments at jepistons.com

Awesome opening round of MotoAmerica Twins Cup for the Chief's Racing Team with a P2 in race 1 on Saturday at Barber Motorsports P#PoweredByJEdb#reposteGreg Reisingerng996

MotoAmerica Twins Cup race 1 was pretty killer for CRT rider Cassidy Heiser as you may be able to tell from the pics. Cassidy loves to ride in the rain and it showed today. It was not without drama. There was a technical problem that prevented him from making it out for the rain familiarization laps. He made the best of it, went out and rode a very smart race and got himself and the team it's first MotoAmerica Twins Cup Podium, finishing in 2nd! A great day the team won't soon forget.
