The Driveshaft Shop aluminum driveshaft specified for Pontiac G8 applications with a TH400 transmission is a 3.5-inch unit that uses a direct-fit rear flange for installation. Built to replace the factory driveshaft for this transmission pairing, it is offered as a purpose-made, vehicle-specific shaft intended to restore proper driveline fit and balance without requiring modifications to the rear flange connection.
