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. Our fully staffed, climate controlled QC (Quality Control) department utilizes the latest equipment to ensure the highest quality Pistons available anywhere.
3 (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 our product before it ever sees a racetrack. Furthermore, the lessons we learn through our involvement in racing series like NASCAR, IndyCar, NHRA and many others, translate directly into the high quality, precision custom and shelf Parts that we offer to you, our investment in technology and equipment is an investment in our future as well as our customers .

9 SHELF PISTON TERMINOLOGYFSR (Forged Side Relief) forging designs feature a reduced skirt width and shorter wrist pin when compared to traditional full round style forgings. The narrow skirt helps minimize piston contact with the cylinder wall that can cause friction and power loss while the shortened wrist pins reduces the overall weight. Some FSR forgings feature internal and external bracing to provide a more rigid construction while minimizing overall weight. with thousands of race miles logged in the most demanding applications like NASCAR, NHRA Pro Stock and Indy Car, these Pistons provide the ultimate combination of low-friction, lightweight design with increased stability and strength.
