JE Pistons 4.6L 2V PRO KIT FT - 271106. JE Pistons is the largest manufacturer of custom-forged racing pistons in the world. Their pistons are designed, forged, and machined in-house, allowing control over every step of the production process. JE’s implementation of the most advanced CNC machining technologies available, emphasises their commitment to delivering the highest quality pistons, pins, rings and components available today. JE's involvement in racing series like NASCAR, IndyCar, NHRA and many others, translates directly into the high quality, precision custom and shelf parts they produce. JE utilises F.E.A. (Finite Element Analysis) to predict the thermal and structural stresses a piston will experience before it gets into service, enabling them to test and race simulate each product long before it gets anywhere near a racetrack. SRP Professional pistons combine forged piston durability with modern performance technology for an extremely capable forged piston kit that doesn’t break the bank. Forged from 4032 aluminum, SRP Pro pistons experience minimal thermal expansion, making them perfect for a high-performance, reliable engine build from the track to the drag strip. All SRP Pro pistons include premium ring sets, wrist pins and locks. As with all JE Pistons products, SRP pistons are made 100% in the USA.
