Yella Terra GM LS 6-Bolt Heavy-Duty 168T Billet Steel Flexplate — YT 9927
Yella Terra’s CNC-machined billet-steel flexplate is designed as a stronger replacement for the factory pressed-steel flexplate in compatible 6-bolt GM LS automatic-transmission 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.
