JAmodified applies over 10 years of experience in designing and manufacturing high performance racing pistons. Each piston is designed utilizing the latest in CAD software and finite element analysis (FEA) and manufactured from enhanced 4032 alloy. This material features low thermal expansion, excellent wear resistance and a higher thermal conductivity. All of our pistons are created using a 2 or 3 step forging process (depending on the application) which yields the finest structural grain orientation and the strongest piston possible.
