When Marlon Mitchell of Fly Ford Racing called us about this innovation from Dynotech Engineering Services, we had to see it. From the factory, '05-'10 Mustangs are fitted with a 38-pound, two-piece steel driveshaft supported in the middle. Only Ford driveline engineers know for sure why Mustang is fitted with a two-piece driveshaft, but you can bet it is centered around reducing harmonics. Ford wants you to enjoy a smooth ride.
Dynotech's one-piece, fully articulating aluminum driveshaft not only simplifies your modern Mustang's driveline, it gets a whole bunch of weight out as well.
Installing the one-piece Dynotech driveshaft is something you can do in your driveway or garage in about one hour. We're visiting Fly Ford Racing in Southern California for a closer look at what's involved and what this shaft does for performance.

1 One-piece T-6061 3.5-inch aluminum driveshaft technology is now available from Dynotech Engineering Services for ’05-‘10 Mustangs. This is a terrific piece made to high standards and dynamic balanced at more than 5,000 rpm. Aluminum construction means less rotating weight and more power to the rear wheels.
