JE Pistons opened its doors for business in 1947 with one simple objective, to supply the racing community with the highest quality pistons and components available in the marketplace. Although times, people and equipment have changed, their objectives and goals 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 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. JE’s implementation of the most advanced CNC machining technologies available, emphasizes their commitment to deliver 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.
JE designs are specifically engineered for extreme applications up to, and including, professional competition. In this environment, the higher compression ratios, highest boost or heavy nitrous usage necessitate the higher tensile strength 2618 aluminum alloy. Features: Dome/Dish requires no deburring or preparation and feature smooth flowing radii for excellent flame travel. Pin fitting, wire locks, and rings included
