New SpicerĀ® D-Series Steer Axles

Enable Improved Stopping Power with Reduced Weight

Mar 27, 2014

LOUISVILLE, Ky., March 27, 2014 – Dana Holding Corporation (NYSE: DAN) today announced that the company has developed an innovative new family of Spicer® D-Series steer axles that will enable improved vehicle stopping power and reduced maintenance without the added weight that typically results from specifying air disc brakes.

Available for applications with gross axle weight ratings from 10,000 to 14,600 pounds, the new Spicer D-Series steer axles will feature an integrated air disc brake (IADB) knuckle that allows fleets to specify air disc brakes without a net increase in weight over most S-cam drum brake axle systems.

By eliminating a separate torque plate and fasteners, the new IADB feature maximizes the integrity of the axle and brake system, eliminates up to 76 pounds from the steer axle assembly, and reduces vehicle assembly time.

“Air disc brake popularity is on the rise,” said Pat D’Eramo, president of Dana Commercial Vehicle Driveline Technologies.  “We are pleased to offer our customers the opportunity to improve the performance, maintenance, and safety of their vehicles without sacrificing payload and fuel economy.”

The new steer axles build on patented, market-leading advancements used throughout Dana’s line of Spicer D-Series axles, including two-drawkey king pin retention, tie rod end sealing, and a lightweight beam.  These features work together to enhance durability, reduce maintenance, and improve alignment capability.

These Spicer D-Series steer axles are the latest in a long history of patented innovations engineered by Dana to help commercial-vehicle fleets save fuel and reduce maintenance.  At TMC last year, Dana introduced the Spicer® AdvanTEK® 40 tandem axle system and higher torque-rated Spicer SPL® 350 main driveshaft and mating SPL® 250 inter-axle shaft.  A 2014 Automotive News PACE award finalist, this system features a market-leading design for a variety of Class 8 applications that increases fuel economy, improves reliability, reduces vehicle weight, and decreases total ownership costs.

At MATS 2013, Dana launched the Spicer® EconoTrek™ 6x2 tandem axle, a durable, lightweight configuration that improves performance, reduces maintenance, and increases fuel economy for heavy-duty line haul tractors.

Dana received a 2013 Automotive News PACE Award for the company’s Spicer® Diamond Series® driveshaft, the first to combine dissimilar metals, successfully pairing steel end fittings with a single-piece, high-strength aluminum tube. The new design can also eliminate the center bearing used in traditional two-piece driveshafts, reducing component wear and installation costs.  As a result, this technology can reduce vehicle weight by up to 100 pounds, improving fuel economy, load-carrying capacity, or both.

Dana is featuring the new Spicer D-Series steer axles in booth 30455 at the Mid-America Trucking Show this week.  For more information, visit
