Dana expands Spicer Diamond Series driveshaft product line


Dana Holding Corporation has announced it will be expanding its award-winning Spicer Diamond Series product line to allow weight conscious heavy duty vehicle customers to benefit from the lightweight characteristics of its Diamond Series technology.

Dana is a world leader in the supply of driveline products, power technologies and genuine service parts for light and heavy duty vehicle manufacturers.

“Our customers are looking for ways to be more productive,” said Steve Slesinski, director of global product planning at Dana. “The Diamond Series can now address approximately 60 percent of North American truck applications with the durable and lightweight characteristics they demand.”

Made possible by Dana’s new proprietary design and manufacturing process, the Diamond Series driveshaft is a robust aluminum tube with industry proven Spicer steel end fittings that can now support customers using driveshafts as long as 130 inches.

The driveshafts - up to 100 pounds lighter than a traditional 2-piece steel driveshaft system - have service free offerings for low maintenance operation.

The innovative design has lower mass, improved u-joint cancellation and eliminates start-up shudder issues for reduced noise, vibration and harshness (NVH).

The driveshafts also feature an improved attractive aluminum finish with inherent corrosion resistance properties.

“Dana Holding Corporation has distinguished itself as the technology innovation leader in the driveline manufacturing industry,” said industry analyst Kumar Saha at Frost & Sullivan.

Recognized by Frost & Sullivan with the Technological Innovation award, the Diamond Series driveshaft is an industry-first, one-piece aluminum driveshaft that now utilizes two Dana patented manufacturing processes to significantly reduce weight while maintaining the strength of an all steel system.

The result is a very robust and significantly lighter driveshaft for improved fuel efficiency and freight hauling capacity, according to Slesinski.
