Piston making has been in the Jahn family for longer than sliced bread has been sold, since 1912 when the JE Pistons™ founder's father ran a foundry with the tagline "Nothing but Pistons." The same expert craftmanship and dedication that was put into those original pistons are still put in the ones that are made today, granted today's pistons are made with state-of-the-art CNC milling and forging machines. All JE™ pistons are designed, forged, and machined in-house to ensure total control and quality in every step of the process. JE Piston Kit Rings Pins FSR 3mm OB 98mm Bore 13.5:1 was expertly forged and crafted to ensure that it stands up to the toughest tests.
