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.

Another VW 2.0L TSI rebuild getting equipped with a fresh set of JE Pistons 🏁 JE sport compact piston designs are specifically engineered for extreme applications found in professional competition. The higher compression ratios, turned up boost, and heavy nitrous usage necessitate the higher tensile strength found in our 2618 aluminum alloy.

We prioritize quality just as much as performance. Once our pistons are forged and machined in our US based facility, they are sent to our in-house quality lab for inspection. Our Zeiss CMM (coordinate measuring machine) equipment is used to examine the pistons for critical dimensions to ensure a quality product in every box. #jepistons #Quality #performance ...

Piston skirt coatings are purpose-designed to enhance the base piston material in a specific way. Some coatings increase thermal protection, others, lubricity. The uniform idea behind each is a that the coating offers some innate advantage raw aluminum does not. Take a brief look at our range of skirt coatings and discover which is right for your next build.
✅ TUFF SKIRT - Our trademark coating that is a lubricating, anti-friction/anti-wear coating applied to the piston skirt only. Unlike our standard Skirt Coating, Tuff Skirt will not wear and is designed to withstand many different types of endurance applications.
✅ Perfect Skirt - Three-times thicker than traditional skirt coatings to allow racing pistons to have tighter piston-to-wall clearances similar to OEM applications. This decreases piston noise on startup and reduces cylinder bore wear as it continuously conforms to the shape of your cylinder's bore.
✅ KoolKote - An aerospace quality hard anodize applied to all surfaces of the piston with a buildup of .001. This coating will withstand greater temperatures and will not flake, chip or peel. Commonly found in use for nitro-methane engines to endure the extreme corrosive effects associated with that fue#techtipsh#Pistonss#forgedpistonss#pistontechn#jeh#jepistonsstons

Cleta Platt-Gibson For John.
Adding boost or spraying nitrous on your stock bottom end? Stop 🛑 relying on your OEM pistons and start looking to upgrade with a set of JE forged pistons. Our pistons are purpose built to handle the extreme cylinder pressures found in high-performance engines, bringing unmatched strength and durability over any cast OEM piston!
