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

  • Fully balanced and rebuildable

Installation of this kit is quite simple includes simple direct bolt-on installation instructions with supplied adapter plate & bolts and should take no more than 1 hour to complete.

LAKEWOOD Driveshaft SAFETY LOOP, 05-08 MUSTANG (all)

A DriveShaft Safety Loop at a price you can afford!

A broken U-joint or driveshaft can cause heavy damage to the underside of your vehicle, sending the driveshaft flying, or allowing the driveshaft to drop down and dig into the pavement, flipping you over. The heavy steel structure of Lakewood driveshaft safety loops can prevent all that, by containing the driveshaft after a failure, allowing you to make a controlled stop with minimum drama. .

Made from 1/4" thick zinc-plated steel, this Safety Loop features easy bolt-on installation without modifications, and is both NHRA and IHRA legal.
