Yella Terra Ford Barra BA–FG/FG-X 4.0L Chromoly Heavy-Duty Flexplate — YT 9921HD
Yella Terra’s CNC-machined billet-steel flexplate is designed as a stronger replacement for the factory pressed-steel flexplate in high-output Ford BA–BF and FG/FG-X 4.0L Barra turbo and naturally aspirated automatic applications. The rigid billet construction is aimed at high-output street, drag and motorsport combinations where torsional load can fret or distort the OEM plate.
