DSS Mazda 1993-1995 (FD) 1-Piece Aluminum Driveshaft MZSH5

This is the Driveshaft Shop 1-piece aluminum driveshaft specifically made for the 1993-1995 Mazda RX-7 (FD chassis). If you're looking to upgrade the drivetrain on your RX-7, especially if you're pushing more power or want to shed some weight, this driveshaft is a solid choice. It replaces the factory two-piece setup with a single, stronger unit.

The main advantage here is the material. By using aluminum, Driveshaft Shop significantly cuts down on rotational mass compared to the stock steel unit. Less rotating mass means the engine doesn't have to work as hard to spin it up, which can lead to a slightly improved throttle response. Plus, aluminum is naturally lighter than steel, contributing to overall vehicle weight reduction. This 1-piece design also eliminates the carrier bearing found in the stock setup, which can be a common failure point and a source of vibration on higher-mileage vehicles. The driveshaft comes ready to install, designed to bolt up to your existing transmission and differential flanges.

When installing this driveshaft, it's a good idea to check your transmission mount and differential bushings to ensure they're in good condition. A worn mount can introduce vibrations that might be mistaken for driveshaft issues. This upgrade is a popular choice for RX-7 owners looking for a more robust and lighter drivetrain component.
