About JE Pistons-

JE pistons are all designed, forged, and machined in-house, allowing control over every step of the piston-making process.

The majority of JE's SRP line (Sportsman Racing Products) is made from a 4032 alloy. This gives the pistons exceptional toughness for performance street and some racing applications, while preserving street manners (wear rate, low expansion, low noise).

Today, JE is the largest manufacturer of custom-forged racing pistons in the world. Offering the shortest lead times in the industry and a 98% order fill rate, JE is the definitive source for all of your high-performance needs. The JE complex encompasses the most modern performance piston manufacturing equipment in the industry.

A fully staffed, climate-controlled QC (Quality Control) department utilizes the latest equipment to ensure the highest quality pistons available anywhere. F.E.A. (Finite Element Analysis), which predicts the thermal and structural stresses a piston will experience before it goes into service, enables JE to test and race simulate each product before it ever sees a racetrack.​

JE’s implementation of the most advanced CNC machining technologies available, emphasizes their commitment to delivering the highest quality pistons, pins, rings and components available today. Industry-leading processes like Ultra Crown®‚ a digital three-dimensional piston crown machining process, and Ultra Groove®‚ a machining operation that provides unprecedented flatness of ring grooves (tolerances to within millionths of an inch), are some examples of that commitment.

Furthermore, the lessons learned through JE's involvement in racing series like NASCAR, IndyCar, NHRA and many others, translate directly into the high quality, precision custom and shelf parts that they offer.
