Upgrading a driveshaft with a lighter, stronger and more balanced piece.
You don't need a degree in engineering to understand that it takes more energy to move a heavier item than a lighter one. So it stands to reason that a lighter driveshaft requires less torque to turn it along with the wheels. Even so, simply installing a lighter driveshaft is not the only consideration for you.For details on the finer points of engineering, we sought out some pointers from Dynotech Engineering Services, a company with more than 80 years of experience with rotating assemblies. This firm started out as a contract balancing service business that supported its current parent company Balance Engineering. Dynotech and Balance Engineering were founded by General Motors in 1923 and are based in Troy, Mich.
Today, Dynotech Engineering Services produces products for professional racers and high-performance enthusiasts alike. This means your customers can have the same driveshaft technology used by their favorite NASCAR drivers for as low as $329 (for a steel driveshaft), and in as little as a couple of business days.
After a Dynotech 6061 T6 aluminum driveshaft was fitted on the 1974 AMC Javelin shown here, the most noticeable thing was the significant reduction in weight from the stock piece. Another obvious improvement is in the aesthetics. This driveshaft looks so good that you almost don't want to hide it up underneath the car. No unsung hero on this ride!

Once a shop has reached dealer status, it can maintain that by selling $5,000 worth of product per year.
No single product seems to sell better than others, as many are built to order for custom projects. However, the 2005 and newer Mustangs are popular in many of today's markets, and several dealers stock one-piece driveshafts that replace the factory two-piece units.
