DSS 16 + CTS Auto 8 speed 4in ALUMINUM shaft (some heat shield clearance may be needed) GMCTSV5-A

Driveshaft Shop is well-known for building robust drivetrain components, and this aluminum driveshaft is a prime example of their work for the 2016-2019 Cadillac CTS. If you're looking to replace a worn-out stock shaft or want a more durable option for your performance vehicle, this is a solid choice. It's designed specifically for the automatic 8-speed transmission found in these CTS models.

This driveshaft is constructed from aluminum, which makes it lighter than a comparable steel shaft. This weight reduction can help improve acceleration and overall performance. The 4-inch diameter is a key specification that ensures proper fitment and function within the drivetrain. While it's a direct replacement for the factory unit, keep in mind that some minor heat shield clearance adjustments might be needed during installation to ensure everything fits perfectly and operates without interference.

When you're installing a new driveshaft, it's always a good idea to double-check all mounting points and ensure there's no binding or rubbing. This aluminum shaft from Driveshaft Shop is built to handle the demands of your CTS, offering a reliable and improved drivetrain component.
