Ultra-Light Aluminum Driveshaft Kit

We are proud to announce the introduction of the newest addition to our V6 Mustang page.The all new Ultra-Light Aluminum Driveshaft Kit

The Ultra-Light Aluminum Driveshaft Kit provide a variety of benefits for your 2005-09 Mustang, Mustang GT, and Shelby GT500. The over complicated factory two-piece shaft weighs an unbelievable 42.3 lbs. as compared to 18.2lb. one-piece Ultra-Light Aluminum Driveshaft Kit. This rotational weight reduction alone is responsible for gains of 14+ rear wheel horsepower. Additionally the benefits of Ultra-Light aluminum can be felt and heard in reduced drive line harmonics and vibration. Ultra-Light aluminum absorbs rotating harmonics much more efficiently without the long term fatigue associated with steel or carbon fiber.

    Ultra-Light Driveshaft Features:

  • Tough, lightweight T6061 Aluminum

  • Simple, direct bolt-on installation, with supplied adapter plate & bolts

  • Half the weight of factory steel shaft

  • Dana Spicer 1330-series u-joints
