DSS Pontiac G8 with TH400 Transmission 3.5in Aluminum w/ Direct Fit Rear Flange GMG8SH4-A

Driveshaft Shop is well-known for making strong, reliable drivetrain components, and this aluminum driveshaft for your Pontiac G8 is no exception. If you're swapping in a TH400 transmission, this is the piece you need to connect your engine to the rear end smoothly and efficiently. It’s built to handle the power and keep your G8 moving.

This driveshaft is constructed from lightweight 3.5-inch diameter aluminum tubing, which helps reduce rotational mass compared to a steel unit. This can lead to a slightly improved throttle response and less parasitic drag on your engine. A key feature is the direct-fit rear flange, designed to bolt right up to your G8's differential without needing any custom adapters or welding. This makes the installation process much more straightforward, saving you time and hassle in the shop. The front connection is typically a slip yoke style, allowing for the necessary movement between the transmission and the driveshaft as your suspension cycles.

When you're putting a different transmission into a vehicle like the G8, getting the driveline components right is crucial. This driveshaft from Driveshaft Shop is engineered to be a solid solution for the TH400 swap, ensuring proper length and balance for your specific application. Make sure to confirm any other supporting components you might need for your transmission swap, such as U-joints or transmission mounts, to complete the job correctly.
