JE pistons opened its doors to the public in 1947 with a simple goal, to supply the racing community with high quality pistons and components. Although times, people and equipment have changed, their goals and objectives have remained constant. Today, JE is the largest manufacturer of custom forged racing pistons in the world. Offering the shortest lead times in the industry, JE is the ultimate source for all of your high performance needs.

JE encompasses the most modern performance piston manufacturing equipment in the industry. They apply the most advanced CNC machining technologies available, emphasizing their commitment to offering the highest quality pistons, pins, rings and components available today. Industry-leading processes such as Ultra Crown®, a digital three-dimensional piston crown machining process, and Ultra Groove®, a machining operation that provides unprecedented ring groove flatness (tolerances within millionths of an inch), are a few examples of that commitment.

Our climate-controlled quality control department uses state-of-the-art equipment to ensure the highest quality pistons available anywhere. FEA (Finite Element Analysis), which predicts the thermal and structural stresses a piston will experience before it enters service, allows for race testing and simulation before the product ever sees a race track. Furthermore, the lessons we have learned through our involvement in racing series such as NASCAR, IndyCar, NHRA and many others, translate directly into the high-quality parts we deliver to you, our customer.
