New Spicer® Aluminum Driveshafts are Trucking Industry’s Lightest

LOUISVILLE, Ky. – Utilizing a new proprietary manufacturing process, Dana Holding Corporation (NYSE: DAN) has introduced a new series of lightweight, one-piece aluminum driveshafts for the commercial truck market. The Spicer® Diamond™ Series driveshaft weighs 40 percent less than traditional two-piece steel driveshafts, has fewer parts, and helps reduce in problems associated with noise, vibration and harshness (NVH).

“Dana engineers provide innovations based on customer need and marketplace evolution, creating products and processes that deliver value, ingenuity, and performance,” said George Constand, chief technical and quality officer for Dana. “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.”

Constand added that Dana is the first manufacturer to combine steel end fittings with a single-piece, high-strength aluminum tube, replacing the traditional all-steel, two-piece driveshaft. The manufacturing process delivers a more robust driveshaft with significantly lower weight – up to 100 pounds when compared with traditional two-piece assembly systems. The new driveshafts also include the use of industry-proven Spicer Life Series® and Spicer® Compact™ Series universal joints.

Designed for heavy-duty commercial trucks using two-piece steel driveshafts of 7.5 to 10 feet, the Spicer Diamond Series driveshafts reduce installation costs through the elimination of the center bearing and by reducing part count from three joint connections to two.  Environmental benefits result from the elimination of painting and the metal inert gas welding process.

The one-piece design – without the center bearing and one universal joint – improves vehicle efficiency by reducing component wear, and the use of high-strength aluminum offers resistance to corrosion and improved appearance.

Spicer Diamond Series driveshafts will be commercially available late in the fourth quarter of 2011.
