The Spicer® Diamond™ Series driveshaft weighs 40 percent less than traditional two-piece steel driveshafts and features fewer parts in many applications, as well as reduced noise, vibration, harshness (NVH) – all with the industry-proven durability of Spicer Life Series® and Spicer® Compact™ Series universal-joint designs.

Dana is the first to combine steel end fittings with a single-piece, high-strength aluminum tube, replacing the traditional all-steel, two-section driveshaft.  This proprietary manufacturing process delivers a more robust driveshaft with significantly lower weight – up to 32 kilograms (70 pounds).  The manufacturing process for the Spicer Diamond driveshafts was perfected by Dana at its technology center in Maumee, Ohio.

"Dana engineers innovate based on customer need and marketplace evolution, creating products and processes that deliver value, ingenuity, and performance," said Dana Chief Technical and Quality Officer George Constand.  "The Spicer Diamond Series driveshaft is a prime example of this, offering our customers the compelling combination of a robust and reduced-weight driveline solution that is also environmentally friendly."

Designed for heavy-duty commercial trucks using 2.3- to 3.0-meter (7.5- to 10-feet) two-piece steel driveshafts, the Spicer Diamond Series driveshaft improves vehicle efficiency while reducing installation costs through the elimination of the center bearing; and reducing part count from three joint connections to two.  

The use of high-strength aluminum offers resistance to corrosion and improved appearance.  The one-piece design – without the center bearing and one universal joint – reduces component wear.  There are environmental benefits, as well, because tube painting and the metal inert gas (MIG) welding processes are eliminated.
