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.

What's our secret to making the SRP Pro 2618 pistons so strong? 🤫 Unlike many competitors' offerings on the market, we manufacture each design iteration from forged billet pucks for in-house dyno testing in real engines prior to approving final forging designs. This gives us the opportunity to make small adjustments to the design to provide performance improvements and additional strength before the piston gets added to our roster.
